My sister just asked me if I was "Facebook Friends" with her boyfriend, and kept asking if I talk to him in any other way... I don't know why she's asking this, but is it possible she might be thinking I want to steal her boyfriend? Is she that insecure about her relationship she has to ask HER SISTER!, if she's talking to her man? She knows I'm not that kind of person, although, in the past (and present), we don't get along and have frequent arguments and fights. Still, I don't know why she suspects that about me. I'm the nice sister! In fact, it's always been the other way around, she's usually the one to flirt with my boyfriends. I think... KARMA IS A BITCH! She's insecure because she thinks I want revenge on her.. WOW. *In shock.*
