In my last apartment, one of my neighbors decided we were best friends, would show up at all hours uninvited. I really couldn't stand her, and the efforts dbf and I made at avoiding her were comical (like slipping out the back door while she was knocking on the front). This probably sounds mean, but she was always drunk, and I didn't want her constant melodrama in my life. She was a factor in my decision to move. I've been leery of getting too close to any neighbor since her.
