Replying to Dealing w/ most annoying kid ever

Today I had to deal with the most annoying kid for a whole hour coming home from a track meet. He has the squekiest voice ever and screams straight into your face even if he is only inches away. He was trying to talk about how he's going to Air Force and studying some weird science- which is good in all except for the fact hes in 7th grade. I almost punched the kid but I held back since I knew I'd get in mad trouble, and having recently gotten arrested, thats not a good deal.
