I already posted this thread, but for some reason I think the mods took it off. So I'll try and rephrase it. I was stating my opinion on a website, and someone who I go to school with replied to my post. She disagreed with everyhting I had said, and instead of just saying that, she argued and called my opinion a load of horse poop (I used the nice word.) I have two classes with this person, how should I handle it if he/she approaches me and begins an arguement at school?
