First of all, you must think of a good reason unless you are drunk. The reason can be to go to the city to see a doctor for an injection, or to forget the time when studying, or to have a little accident on the way and be delayed. If you use these reasons occasionally, my aunt will still believe you. Of course, if you have other things to delay, you can also say so. Moreover, the hearts of uncles and aunts are made of meat after all, and they will be more tolerant to the younger generation when they are old, so these methods still work.
In the university dormitory, you must plan ahead, that is to say, thinking that one day, because of various things, you will return to the dormitory, so you should consciously get on well with your uncles and aunts, especially those students who often come back late. It is necessary to send packs of cigarettes from time to time. And according to my observation, some aunts and grandmothers often collect empty bottles and go out to buy them because of insufficient income, so don't throw them away when they drink too much in the dormitory, they can send them over.
Anyway, it is always impolite and against discipline to make a phone call after the entrance guard is over. I am the one who is in the wrong, so if the manager says something, don't worry, just listen. And try not to go back to the dormitory so late. Violation of discipline is one thing, the key is that it is not safe to be outside at night.
