So there's this guy who started annoying me back in the start of 9th grade, and he always talks to me about some shit idaf about. At first, I was nice because he is a high functioning autistic kid, but not like he has to be at the sped table just enough to have a ied. Anyway, it's now 10th grade and he still won't leave me alone. I've tried to be nice I've tried to be rude I've tried ignoring him. For almost a year and a half, he's just kept talking and not caring. So please how do I get him to go away without hurting him severely? (I don't wanna be friends with him because we disagree on multiple political and non-political topics)
