I'm going to tell a kid who I think has adhd to shut up since he was making noise
Why do you want to tell him to shut up?
I can't handle noise, and some kids tend to annoy me and make noise.
It can be hard to deal with noise but you cannot tell a kid to shut up. They might not be able to help it and it will hurt their feelings.
It's not my problem if he thinks I'm mean.
It is if you're being mean to him and if other people see that you're bullying him they will be upset with you.
