Sometimes I don't know how to talk to a student. Even though I'm well aware they are in a hurry or stressed over something they need us to help, some of them might be a bit rude and you have to be as polite as possible but at the same time, they think you are being passive aggressive. This is con from working without having visual contact with the students.
I started working as a tutor 2 and a half months ago, unfortunately, I have attended 2 of 5 rude students. It hasn't been a fully bad experience, but I hope some students were nicer to us. At least in my case, that motivates me to help them as much as I can.
