So I went to a new highschool this year and I started hanging with a new of groups of kids now at first everything was chill but after a couple of months it seems like all the jokes are turned against me and it mostly comes from this one kid in the group he also slaps my neck sometimes and runs away laughing.He is shorter and weaker than me so I feel like it wouldn’t be good if I just tried to fight him. Also this other kid does the same thing slapping my neck and running away but it’s played off as a joke so I don’t know how I should reacted. What should I do?
