I want to tell a 1st year engineering student wearing a lab coat and safety goggles to lectures, that he's so cringy and making a fool of himself
Why would you talk down to this person like that?
Maybe I shouldn't, but I don't care.
I can see why you think his a attire is a little dorky. It's OK to pull him aside and gently suggest he's overdoing it. But being mean and making him feel humiliated is mean.
Damn that's stupid. I don't care what people think and it will hurt his feelings.
You shouldn't be mean to him for no reason. Just let him wear what he wants to wear if that makes him happy.
