What Are Some Times You Encountered A Rude Person?

What Are Some Times You Encountered A Rude Person? I’m 19 currently in college. I’m pushing myself socially and I’m having a lot of experiences so fast. Some are good and some are bad. My brain seems to focus on the negatives more than the positives. I know I’m still working on it but, please share experiences/tips you may have. YOU ARE ALL LOVED ❤️
