both of my sons have left and come back, one did it twice. He might be back again this very year, as he is withdrawing from grad school and losing the lease on his rental all at the same time this spring. He has to make the huge leap of finding a place to live AND a job in a short period of time and he's never been a fast mover; so I'm fully expecting to see him show up at our door so to speak.
