I doubt if my daughter would find herself in a situation where she'd have to move back home.
My son is a different story. His favorite saying is, he knows what he is doing. Unfortunately, when it all backfires, he comes to us looking for help!!!
He is getting married in May and she is a very independent person. Even so I expect there to be moments when they need a little help and that is fine--even welcomed. But since she is a very stand on your own feet type person, hopefully we lost the roll for the big major things in life.
