shut the fuck up you stupid douche. but honestly bro I have the same situation, not as severe but similar. This kid at school follows me and my buddies every time we go to lunch or hang in the cafe or gym. he goes on all the ski trips because we do and he tries to get in all my classes. I just told him off the other day, he has other friends to annoy so he can bug them instead of me. I told him to stop following me around, and to fuck off.
I don't know if you should be severe as that but it works for me, I think if my old man didn't like this kid and his old man, I would tell him off for sure because its one thing if he follows me and bugs me, its another if he is bothering my old man.
And if you like Sunday River, don't let this kid ruin your time there. Just blow him off, and if he follows you, go to the chalet and ditch him.
Hope it helps.
