Would I Want a Big Sister

Who's sometimes nice, who's sometimes mean. who thinks she is best, at most everything. Who believes in the saying, "First is the worse and second is the best" who wishes of her big sister, she had less. Who lets her anger out, in pinches and scratches, who would try to force me, to light matches. Who would want to stay up when I wanted to go to bed. Who when she got mad, she would slap me on the head. No, I wouldn't want a big sister, who would cause so many difficulties. But,Wait, does that big sister sound alot like me?
