My sister used to gripe at me that I was never home and didn't act like part of the family. My dad started agreeing with her, too. And finally one day I asked what exactly the requirements were to "act like a family member." Because as far as I could tell it was:
~Sit in a separate room from anyone else and interact as little as possible.
~Yell and scream constantly
~Never say anything positive
~Act like I'd rather not be around anyone in the house
So with those qualifications, why would I stay home? I found friends who acted like they wanted me around. Nothing wrong with that.
