Every morning, I have to take a crap and I always get to the bathroom before my sister does. When I am finished taking a crap, I never flush the toilet. When my sister goes into the bathroom, the toilet seat is up and there is shitty toilet paper and a couple of big turds in the toilet.
My sister screams and calls me an asshole. I told her to shut up and flush the toilet. She hates when I don't flush the toilet because she sees my shit and the bathroom reeks of shit. I love it when I do this.

Does anybody else do this to her sister?
