Today I am thankful for my sister. Lately we have been stepping on each other's toes, but she is still great. We're bound to drive each other crazy working and living together all the time, but we still manage to have a good time when we hang out. She puts up with my crap, and I put up with hers, and we both know when the other is full of it, LOL.
I read a great quote once that definitely defines my relationship with her. "A sister is like a best friend you can't get rid of."
