Tell me about the wonderful living habits of roommates that make you speechless?

I have a roommate in college, and there is a behavior habit that everyone in our dormitory can't stand! At that time, the toilet in the dormitory was squat-pit-type. Such a big hole was disgusting to say, and it might be blocked if it was pulled wider at ordinary times.

My roommate always throws toilet paper in the toilet after going to the toilet. As a result, the toilet was blocked at both ends for three days. The process of getting through the toilet was disgusting, and even the water in the toilet was blocked once. The toilet is full of yellow shit. I can't eat for several days at the thought of this scene, and even the dormitory is filled with an unpleasant smell.

We warned her several times about this, but she couldn't change her habit for a while. Every time she goes into the toilet, everyone will shout through the door and throw the paper into the wastebasket! To remind her, for fear of another tragedy. In the four years of college, we really can't count the number of times we went to the toilet. Think of all the bitter tears.
