I don't want to talk to Harry right now because he is being very pompous.
Does his attitude upset you?
He is always proud of what he says and blames others without any reason.
You have free will for a reason. You don't have to talk to anyone you don't want to.
Last time I checked, we are forced to be at school with each other and can't leave if you don't want to be around someone.
You can talk to other people In school there are a lot of other people in your class.
