Sometimes papers are homework, and sometimes papers are exams. Whatever it is, it will affect your grades. So I think the paper is still very important. It is important to protect yourself, of course, there is no problem.
I don't think I will judge those who ask to see your paper. Sometimes I just want to find ideas, and sometimes I just want to copy your papers and steal the fruits of your labor. Such people are very bad. Sometimes if you don't show it to others, others will feel indifferent and respect your choice.
However, most of the reasons for this emotion are that you don't want to show your paper to others, so you are accused by them unnecessarily and unreasonably. There are people around me who always want to read others' papers after they are finished, or others finish them first, so she plays while they are writing, and she wants to borrow their papers and hand them in as soon as they are finished.
I don't like such people very much. Don't respect other people's labor achievements, don't respect teachers, and don't respect their own studies. But if you don't show it to him, he will get angry and say that you are stingy in front of others and don't even share a paper. At this time, you will feel wronged, but when you know that you have done nothing wrong, you will be accused by him and your reputation will be damaged. I feel very helpless and wronged.
Although I have to bear such helplessness and injustice, I will not change my practice, because it is no problem not to show my classmates the papers.
