Don't you despise it when you feel like you trust someone and then they hijack all your presious material posessions. I had a friend whom I belived was a close one but she dug through my backpack and stole a whole load of my stuff when I was not around. Just figured I'd get out my distaste for the whole thing in type so I'll have an easier time copeing.... It just really irks me....
i used to know a girl who would grab my purse right off my arm, throw it open and rummage through it until she found some stuff she liked, pocket it and then give me my purse back. i was like, what the hell? give me back my shit. she apparently had no idea that this wasn't an okay thing to do, and she was 20 years old. then again, she also would greet people by running up to them and humping them. but what that girl did is really messed up, i'm sorry. is there any chance you'll have to confront her and get your stuff back?
you are hanging around with the wrong people don't associate with idiots or adopt their habits otherwise you eventually become one by pure osmosis.
I have had quite a few "friends" like this throughout the years. People where I live seem to be caught up in all the wicked bs of this world. Even now it seems like most of my old "friends" fom highschool are still living like that with the gossip and all. I think what you are doing with teh cold-shoulder is the best way to deal with it. That is what I did. I actually had one of my "best friends" steal from me and then spread some off the wall rumors about me around our close knit group of friends. I know how this feals, but the old saying is true. It IS better to have one true friend then 100 untrustworthy ones. A true friend will be more loyal to you then a brother... Good luck to you and hopefully you willl replace the unloyal friend with one who will be true... 8)
