he is very annoying and I cant stand him!
Leave him alone. He's already with someone else. Find someone who's single and date them. There's plenty of them out there.
He should leave them alone ! Their relationship is none of his business !
If a boy has a girlfriend then he is considered taking and you should leave him alone and later he may break up with his girlfriend.
tell the supid man to leave the girl alone then punchem
Unless you are absolutely certain he loathes your soul, you should tell him.
At age 10 neither one of you really really know what "love" is all about ... but what you should be doing is telling that boy "leave me alone!" If he doesn't, then you need to talk to your parents and/or your teacher and school principal.
Tell her she ugly.
It all depends on how cute said boy is. If the boy is a Cristiano type, then yes. On the other hand, if he is only semi-cute as in Johnny Depp, then it would come off as a little peculiar that you are going to the same new school as he is.
tell him to puck off
This is coming from a boy if you talk to him and he ignores you it usually means he doesn't like you and you should leave him alone.
tell on him and tell him leave my girlfriend alone.
no but you should stay with them if your not in public aka in your house but in the movies or resturaunt then leave them alone.
