What do you say about weddings that go till late at night?
Rav Miller zt”l: Why should weddings take so long?! You need hundreds of people to ruin their health just because you want to make a wedding?! People should go home early — it’s a crime to keep two hundred people up till very late at night! The next day two hundred people will be walking around looking like ghosts because of you. It’s a strain on the heart and a strain on the kidneys. It’s too much!
The truth is that it’s too much to expect even of a good friend. Even a good friend should sneak out! Don’t bother to go over and excuse yourself. Because then he’ll start importuning you. Just sneak out and forget about it. He’ll be angry? Your body will also be angry at you if you stay, and it’s more important to be friends with your body.
