What shameful experiences have you had when you went to the toilet?

I am a senior three dog who is about to graduate. Looking back on the four years of college, the most shameful thing is that I ran to the wrong toilet. I am a girl. One morning, I went to class. The toilet in the classroom over there is different from what I used to go to. It used to be the kind where men are left and women are right. It turns out that men are right and women are left. Usually a little nervous. I habitually went to the right toilet. I went in and found that the internal structure of the toilet was different from my previous one. I almost froze in the men's room for a few seconds. I realized that I had gone to the wrong toilet and was about to go out. I saw a man squatting in the school toilet (squatting with a door, standing up will leak his head). I also looked at him for three seconds, and he froze! Because it was none other than the boys in our class, my face turned red and I couldn't even run. As a result, I just walked out of the men's toilet, and a group of boys in our class passed by the toilet. I can't wait to find a hole to get into. I have been in college for four years, and the most shameful thing has never happened. haha
