Man, if I were the little sister I think I would have beat him up a long time ago. I like how the siblings all have different dynamics. My big sister and I used to have a relationship like the little brother-big sister one, then we transitioned into the twins'one, and finally we buried the hatchet and actually started to get along for a change. No matter how unsufferable a sibling can get, it's fun to grow up together (unless you have that guy as a big bro)
