My roommate always goes to the toilet and poops and forgets to flush.

What is it like to go to the bathroom after dinner and find that your roommate forgot to flush the poop?

I have always had a complaint group with a few of my best friends in high school. I just woke up today and saw it. A girl was complaining about how a girl in their dormitory forgot to flush the toilet after going to the toilet, and when she came back from eating, she went to the toilet and was disgusted. I wonder what kind of emergency situation would it take to forget to flush the toilet.

In order to solve this problem, our method is very simple and crude. We ordered placards on Taobao and directly posted them on the toilet. If I forget them again, I really want to hammer them. We have already agreed that if he behaves like this again, we will beat him.
