I sit near two girls who talk during the entire lecture and bother everyone around us. The thing is they are both mean and no one wants to confront them so people just end up moving to another seat. I do not want to change seats!! So I sent them a note and asked if they could stop talking because it was bothering the people around them. Well I successfully strongly angered them both and I am not sure that my note worked THEY ARE STILL TALKING!!! What should I do? thanks
