What should I do when I meet my students (junior high school students) in the street, laugh or talk?

Why are you embarrassed to meet the student union? Do you feel that when you meet a classmate, you don't know if you want to stay and talk, but you have nothing to say? Pretend not to see them, okay? Another is that I didn't talk much before, and I didn't get along very well. I didn't know how to do it. This is not embarrassing, but I don't know how to do it, right? It depends on what kind of situation you belong to. If it is the first one, you can say a few irrelevant words with a smile and find an excuse to leave. If your classmates come to tell you, you can also say a few ordinary and distant words and find an excuse to leave. It will make you meet awkward classmates. You didn't play very well before anyway, did you?
