Tell a really funny story around you?

Tell you a true story. It happened when I was in high school. At that time, we lived on campus and the dormitory was on the second floor. At that time, we especially liked to go to Internet cafes to play games all night. Usually after the teacher checks the bed, we tie the sheets to the heating pipe and go downstairs along the sheets. Over time, a row of black shoe prints appeared under our window. The school teacher noticed and arranged for the teacher on duty to catch us at night. That day, several roommates discussed going out to play. After observing for a while near the window, I found that the patrol teacher came over and began to go downstairs one after another. After they got off the sheets, I pulled them up and closed the window. After about five or six minutes, I heard someone shouting downstairs. As soon as I opened the window, I saw the boys come back. Followed by the teacher, let me throw the sheets down and let them climb up. After I threw the sheets down, they climbed up one by one.

Later, the school put guardrails on the windows on the second and third floors to prevent us from going out to play again. Later, it was quite scary. What can we do if something happens? Friends who are still at school, don't do things like us again.
