The chazan skipped Tachanun, and everyone assumed there was a chatan or a brit. After davening, the chazan said he just forgot Tachanun. People disagreed about whether we could/should say Tachanun at that point. What is the halacha?
Is it permissible to read a book after the bedtime Shema/Hamapil? I like to read in bed before falling asleep, but I sometimes fall asleep and, if I have not said them beforehand, it is possible that I will sleep through the night without reciting them.
