Don't come to the Beit HaMikdash on Chagim without a Karaban. You must show up with to the Temple with a sacrifice.
When you travel to your cousin's Bar Mitzvah, do you bring a gift? Exactly. And now you bring nothing to Gd?! Shame.
Bring a gift.

If we learned anything, be a decent guest. You're visiting Gd's house. Don't show up empty handed. Nowadays, people bring letters to the Kotel. That's not a gift. There's no Mitzvah for that. No host needs a postcard from a friend who's looking to get married, but can't go out of their way to visit.
Hosts want food. You show up to dinner with a dish. You show up with a note that says 'please forgive us for not bringing anything,' you're not getting invited back. Well, that's what you're doing at the Kotel. You're bringing a note that says something went wrong and you're sorry.
Nobody likes people who show up without a gift. You show up to the Temple with no meat, and then to top it all off, you don't have the first fruits basket. You're a Temple taker, and the Kohens are all starving and acting real smug.
I am not suggesting to have a barbecue at the Kotel. It's not the Temple.

Bringing nothing is a huge letdown to the hosts. I've been witness. 'Mark is here... Oh shoot. He brought nothing. He's just a letdown... I thought he makes a nice stew too... Nope. Nothing. Not even a gazpacho... I think he knows we invited him. He's here. We won't have him again. Come in Mark. Take off your shoes. Only people that bring a gift can leave their shoes on... I know we invited him, honey... Didn't he at least bring wine?! Nope. Nothing. Just here to eat. To live off the fat of the land. No appreciation... Wine and stew shows appreciation, Mark. We're having Matzah for dinner now.'

A sacrifice is a lot of meat. The problem is most people show up with dessert. There is no commandment to bring a babka. Anybody can afford that. It would be much better if people showed up with a nice roast. If you're eating at our home, bring a roast and you will have an excellent dinner.
Why people host that can't cook is a different story. And don't show up to my house with a broccoli lokshen kugel. A broccoli quiche is OK. If it's in lokshen form, it should be spinach. Spinach lokshen kugel is excellently tasty. I don't believe that is a commandment in the Torah, but it should be. It would make us happier. Spinach lokshen kugel and a roast. If you're eating at our home, we'll provide dessert. You provide the spinach lokshen, roast and wine.

If we've learned anything from this Mitzvah, never depend on the hosts to feed you.

Make your wife happy the first year.
After the first year, don't even try. It won't happen.
For one year you should make her happy. After that, you can be honest. Complaining about her cooking is suggested. After the first year, there is no reason you should be eating dried out corned beef anymore. Arguing about the kids after the first year of marriage is also tradition. You will want to blame her side of the family for anything that is off in the child.
For the first year you have to smile. After that, football games are the best way to spend your time. TV should be running all the time. Don't even try to make her happy after the first year. She married you. It won't happen.

The Pasuk teaches, (Devarim 24:5) ‘When a man takes a new wife, he shall not go to the army, and not obligate himself to anything. He shall be free for his home for one year, and he shall make is wife whom he has married happy.’
It's already enough to try make his new wife happy. We don't want to throw anything else on him, like war.
After the first year, get out of the house as fast as you can. Problems start after the first year. At that point, you should be hanging out with the boys. That's how you keep a marriage together.
After the first year, it’s better he goes to war. Usually, the wife insists, ‘Get out of the house and do something.' Many times they request the husband goes to the frontlines.
Once the fights start, that's your sign to get out. Enlist. War is preferable. It allows you more time out of the house. And there is less fighting in war.
Many fights have been caused by the 'not obligating himself to anything' part. Many husbands have used this as an excuse to relax for the year. Wives have used 'a good for nothing' to describe their husbands who keep this Mitzvah. 'He's a good for nothing.' Once she starts calling you a good for nothing and yells at you for not having a job, that's when you should go to war. Join a tank unit. It will be harder for her to find you there.

How many old wives does he have? That’s a question. That might be why this new one is mad at him.

The most important take away from our Mitzvah today is to not try to make your wife happy after the first year. That is too much already. And as we know, you can't ask somebody to keep a Mitzvah that's impossible to do.

It's a  Mitzvah to permanently place a Mezuzah. As it says (Devarim 6:9, 11:20), ‘And you shall write on the doorposts of the house.’
This Mitzvah caused much anger amongst the parents pf the Jewish people. Their kids learn this Mitzvah at school, and they come home and destroy the house. They hear to write on the doorposts and they can't wait to get home.
I can't tell you how many times I've heard parents reprimanding their children, 'You’re killing the door. What are you doing?!... Go to your room and don't write on it.' To which the educated child responds, 'The Torah says…' And then the kid is taken out of Jewish day school and sent to public school. It happens time and time again.

At first they thought their kids were using erasable whiteboard markers. Who would command anybody to ruin a beautiful doorway?! When they found out the kids  were using Sharpies, all Gehenim broke loose. Parents were outraged. 'How can H' give such a commandment?! It's enough that we measure the kid's height on the doorpost once a year.' It turns out that measuring a child's height is not a Mitzvah in the Torah. Even so, many doors have marked growth of children.
Once a child reaches Mezuzah height, tradition is to stop marking the doorpost.

This misunderstanding of the Mitzvah by elementary school kids and art teachers is why the Mezuzah box was created. A box to hold the words of the Torah that are permanently affixed to the door. This way the kids can do their art on that and don't kill the doorposts. So many ancient homes in the Ottoman Empire were destroyed by Jewish children and their graffiti.
To this day mothers have to yell at their kids, 'No. Don't write on the wall. Here. Decorate the box...' Sometimes they even give them a little slab of wood to draw on, so that the kids can be creative on a future Chanukiah. Since the Mezuzah fiascos of permanent poor outwork on lintels, we have developed many festival art opportunities for holidays. They create Sukkot decorations, Purim masks, Pesach Seder plates. Now kids force us to hang their artwork, as commanded by the Torah, destroying the Sukkah.
Next time, we will talk about how people have misunderstood the Mitzvah of Hiddur, beautifying the Sukkah with the artwork of third graders. We will also discuss ways in which to throw out the pathetic art the kids bring home from school.

The Rambam teaches that to do Teshuva (repentance) correctly, you must confess (Viduy) and say 'I will never do it again.' We learn from here that the most important part of repentance is to lie.

Rambam Hilchot Teshuva 1:1 To do proper Teshuva, you must do Viduy which consists of ‘Please H’, I have sinned by accident, I have sinned purposefully, I have sinned in defiance, before You. And I did such and such. And I regret and am embarrassed by my deeds. And I will never return to this again.’
Hence lying is the essence of Teshuva. You have to lie to God with sincerity. ‘H’. I feel so bad for having a good time. I will never do it again… Or at least until after Sukkot, when You stop judging us.’

This guy seems to have done every sin imaginable. The real question is, what is 'such and such'?
'Such and such' is a long list. It usually starts with eating chocolate. Chocolate seems to be the biggest sin people are worried about. That's why you hear about vows of not eating chocolate again when it comes to New Years. 
Other such and suches are 'I had the best burger of my life at Wendy's.' 'I watched too many series and didn't learn enough Torah.' 'People needed me and I enjoyed myself instead.'
I've got to be honest. If somebody every tells me they did such and such, our relationship is over. Nobody does such and such to me and gets away with it. It's rude.

Have you ever heard anybody regret something and not do it again? No. People always eat chocolate again. 
The statement my congregants should make is, ‘It will never happen again till Sukkot, when I forget about it.’ Or 'I would've never said that if I wasn't worried that I would be written in the book of death.' Or 'It's my rabbi's fault. I blame him for everything.'

I pray for all that you will be able to celebrate full repentance, and stick to your lies, so you don't end up in Gehenim. And those lies should have you written in the book of life, enjoying chocolate.
