My friends think I like this guy when I don’t even like him AT ALL…?

I’ve never had a crush on someone. I’ve never went out with someone. I guess I’m just not into that part of my life yet. But today something was different and now I’ve got a headache. I was doing sport and we were playing volleyball. I’m not good at sports, I’m pathetic at it. I can’t hit the ball over the net. In Homeroom, the teacher made everyone sit in alphabetical order and I have to sit next to this guy. He’s always annoying me, saying random stuff and sometimes keeps tapping me. I know he just want to play around and I know h doesn’t like me, he just want to mess around. Well, my teacher knows that so today while I was playing volleyball, she said to “Use your muscles; pretend the ball is (the name of the guy)..” When she said that, everyone started laughing at me. Also, ever since that, my friends have been teasing me about him and saying that I like him when I have no feelings for him. It’s so annoying,. I just feel like hitting them. They think it’s a big deal since I’ve never liked someone before. They’re such b*******! HATE THEM!!! WHAT SHOULD I DO???
