I have a brother who's 4 1/2 years older than me. For the first 13-15 years of my life, I was his favourite chew toy. -.- Bullied me to no end, he did. And I wasn't passive in that either, since I tended to try to get him back. (Key word being try.) But once he moved out of my parents house, our relationship started getting much better. Now, he lives on the west coast, and I live on the east, and we very seldom speak to each other, but we get along fairly well. Last time I saw him we got into a shouting match and damn near started a fight, but a few hours later, everything was chill. Basically, what I'm saying is my brother and I get along pretty well. No, really, I mean it. Everyone has their own way of interacting with others, and the same goes for siblings. What works for some people might not work for others. Just try to be a little more honest about how you feel with your sister if you want to be closer to her. It might just be all the both of you need to get the ball rolling. Or we could just trade.
