Because you'd ask things like when is he going to marry me! You don't take into consideration that maybe I don't want to be married. Or maybe I'm not ready to subject him to the weirdness that is our family. Maybe, just maybe, this is something of mine, that I like to have all to myself, without it becoming dining room conversation. Maybe because I'm an adult who doesn't need someone else to approve who she likes to kiss!
You know, I was starting to think that maybe you did care about me, as a person and a sibling, and it was sort of nice to have a relationship where there was never one before. But I think I was wrong. I think you just don't like someone messing with what you consider yours.
