She studies the art of it

My roommates are playing roommate chicken again and I always lose.

This is the first night I have been in my apartment for a week and I came home to find the sink full of dishes. Knowing I in theory live with two adults I am not cleaning up after them. I usually observe them being gross before getting annoyed and cleaning it but today it was taken to new heights when I just heard my roommate pour/sc**** soup(?) into the toilet, flush it, and walk away.

We have a garage disposal...
