Yeah, I got in a fight (verbal, very short) with my girlfriend's sister. My GF and I were at her dad's house for Thanksgiving, and on Saturday we were in her room with the door closed (not locked) just talking to each other about some "emotionally heavy" stuff, when he sister burst in through the door without knocking. I told her to please leave right away, and that my GF and I were in the middle of something. She got this enraged look on her face and stormed out of the room, slamming the door very hard behind her. A few moments later I heard her yelling something about my GF being "her sister too" and that I was "stealing her away from her." I've been with my GF for 3 years now, and I've since learned, after attending many family get-togethers, a reunion, and this Thanksgiving, that my GF's sister is regarded as being the "difficult" one. She's 21, but acts 10.
A few seconds later, I heard a CRASH outside the door (my GF and I were still in the room), and I opened the door to see a pile of stuff outside the door. It seems whenever she and I get in a fight, she likes to take my stuff from one place, and throw it outside the guest bedroom door. Only this time, only one thing in the pile was mine, which was a brand new Airport Express that I had bought for my mom. Luckily, it was still in its box, so I don't think it got damaged.
Usually, when my GF's sister and I get in fights (she's never liked me, she says it's because I'm male

) I just take a deep breath and leave her alone. But this time I felt she had gone too far, and I confronted her about it. I put on my best "I-am-so-ticked-off" voice, and loudly said "Deanna (her name), you WILL treat my belongings, and those of others, with RESPECT!" She yelled back for me to f****** shut up, and go away. Her dad, who was nearby, told her to grow up and to now throw my stuff around (actually, half the stuff she threw was his). She got even madder, and stormed outside.
I thought it was over, but later I was surfing on My Space and found a very nasty blog she posted on her page saying some very mean and untrue things about me. She blocked me on My Space so I can't even post a comment on the blog to tell my side of the story. Needless to say, I am really, really ticked off at her.
Now there's a story!
