College students have first reached the age of 18. Legally, I am 18 years old and can be responsible for my actions, so I can choose to spend the night outside. However, in order to stipulate the school discipline, the school is not allowed to leave school at night, so the guide should ask for leave in advance. As long as you want the guide to put forward your own ideas, the guide will agree to your request. Moreover, this is something that we all have to face. We are adults. We can make our own decisions about many things, but we must abide by the rules and laws. At the same time, we should also pay attention to our own safety, and everything should be based on our own safety.
