ok-am I being unreasonable?

The bathroom topic...I can not stand a gross bathroom. I am always straightening my hair and whatnot so it's a given that my long hair will be all over the floor and the counter and everywhere. But I kid you not, I clean the bathroom every time I am finished using it. I'm talking spraying the counters down and everything. My brother on the hand is an absolute slob and shaves and leaves his hairs everywhere and his dirty football clothes everywhere. I just throw it all in his room. I hear you though...girls can be really vicious in the bathroom. Millions of bottles and stuff everywhere. If I hit some of my friends, they would probably get really upset and cry or something.
