WOW, so true.
Here is probably something you don’t know or realize either. The shelichim are probably connecting to some of the other boys as well. Keep breathing and let them do what they know how to do best. You do your part, let them do their part, and keep praying that your son does his!
But here is a question for you, when you say “yeshiva with a dorm” how does he actually fit in to that? I can see that happening with a place like Home Sweet Home and Avi Fishoff because those boys want to change and it is NOT a yeshiva, but he doesn’t want to sit and learn, he doesn’t want to be a part of that life, so what Yeshiva doesn’t require learning and being shomer Torah and Mitzvos? Please don’t convince yourself that it is what he needs right now and set yourself up for a huge disappointment.
