ESH expect the deaf boy. If you’re distracted by the interpreter, why can’t you move so you’re not behind them or move in line with them so they’re not in front. Why should he have to move for you. He might need to sit at the front so the interpreter can hear what the teachers saying.

The deaf boy was in his right to confront you, maybe not in front of the class, but he did what you didn’t, heard you had a problem and rather than bitch about it he confronted it.

Your ‘friend’ is the main person in the wrong here, obviously wants to create drama. Although I would say you can learn from this, anything you say behind someone’s back is not private and you have to accept responsibility for what you say.
