There are two situations I hear about. The first and most common is that the parents are really sad to be leaving their kid(s) and their relationship thrives. The other one is the person is so ready to leave because the relationship is like mine, a little strained. I actually know of a mom and daughter who have had that relationship and they both said that their relationship did a 180 turn for the better. That's what I hope happens to my relationship with my family, and I think it will. However, since we're really not close as it is I don't know, I think at the least it will become much more cordial. I don't know what will happen but hopefully this changes for the best!
On that kind of depressing note I really want to move to Washington state!
