One: If you don't want to take part in some class activities, you can say that you have diarrhea in college, and the class likes to organize some party activities. I remember when we were freshmen, we often had such activities. For the activists in the class, we naturally like to participate and show great enthusiasm. But for those introverted babies, they really want to avoid it, because this kind of activity sometimes requires performances. Everyone forms a circle, and you perform in the middle. I'm really afraid of blushing. Haha, it's embarrassing. So, naturally, I don't want to take part in such activities. You might as well do whatever you want. At this time, always ask for leave with the organization staff. So what is the reason? It's diarrhea. It can be said that I can't take part in the activity because I ate something bad and had diarrhea. Please approve not to participate in the activity. Our roommate used this kind of sick leave several times, and it was successful, so he didn't take part in the activity as he wished.
Two: If friends come the next day and want to go out to play together, you can ask for leave to go to the hospital to see a doctor. In college, sometimes old classmates will come from other places. At this time, you must accompany them, have fun together, talk about what you saw and heard in college, and renew your friendship. But there happened to be a class. What should I do? It's definitely not so bold to skip class openly. At this time, you can ask for leave. What is the reason for asking for leave? I can't say that my friends have visited me. I want to spend quality time with her, right? This is absolutely not allowed. So you still have to call in sick at this time. This sick leave can be said to have caught a cold last night and needed to go to the hospital for intravenous drip. It is usually possible to ask for leave at this time. I used this method when I was in college. Leave successfully!
Three: There are other reasons for not wanting to be absent from class. For example, you want to sleep and go out to play. When you can't attend class, some students will take personal leave. So what's going on? They all play by themselves, at home, in the dormitory and so on. To put it more seriously, I have to ask for leave to deal with that situation.
To sum up, universities are used to taking time off, except for sick leave.
