Thank you. Yes I agree with most of what you said. He is homesick and keeps on complaining about not having any of his friends around him.
He now has almost a 6 weeks break. He will take this time to figure out if he is ready to give it another chance, hopefully he will. Maybe he will also apply to few schools to keep his options open. But mostly, I think will try to encourage him to join a club if he goes back. Tried to do that but it never went far…
