I got out and buy some nail polish with my own money, and then it gets used by someone else.

I'm sitting at the computer, and smell.. nail polish. I then turn around, and lo and behold, my brother did his nails.. with MY nailpolish, the one I actually went out to buy because I'm broke and can barely buy anything without my mom >.> Finally! Something of my own, and he uses it.. I mean, it was an unexpected use, but man.. grr.
