I rode a spinning bike for a class, my leg hurt badly, and on the third day, it hurt even more, and

It's probably a habit to do this all the time.

When I was a student, I used to urinate frequently. After each class, I used to go to the toilet. However, when other classmates found out, they were ridiculed. >>>More

Let's talk about the points you asked first, a class is 45 minutes, you can talk to the teacher when you go to the toilet, you can also go out quietly, if you form a band, you need to find a venue and musical instruments or something, and spend the night outside, as long as your school is not strict at night, you can be outside. >>>More

Please rest assured, there is no problem, children have a small bladder and drink a lot of water, just after drinking water is very quickly urinated, the next class will be fine, middle school students have to go to the toilet two or three times a morning.

This kind of student is more naughty, you have to be patient.
