I have a friend whose family is, to put it mildly, dysfunctional. She wants to move out but she's a full-time doctoral student and part-time museum guide -- which doesn't nearly generate enough money to be even someone's roommate. Except that now her father has told her that she's 'just like her mother' - whom she despises - and that HE wants her out of the house.
I have a daughter who had a close friend at college last year, but that friend hyper-bonded with her roommate, freezing out my daughter -- and this year she is in the same room as them, getting frozen out all over again. Oh, and its four girls in a room sized for two -- the college wasn't able to get a new dorm on-line in time for this semeter -- so, no privacy, either.
I have to remind myself that I really can't fix these things.
