My maths class :[

A boy who I sit next to in maths is so annoying, there's never a lesson that he hasn't talked to himself once, he smells like someone's wiped spit over him, he nicks my stuff. He's a nice guy but that stuff puts me off everything. I can't move seats...

because there's no spare seats and no one will swap with me because he annoys them too. Half the time I can't even concentrate because I'm working out a answer then he says something and I forget what I was doing. How could I work with him while doing my work?

you should talk to your teacher about it. I'd probably do something mean like tell him to stfu and take a shower, but thats just me :D

You should definitely talk to your teacher about it. If he's affecting your learning, something needs to be done. Just explain the situation to your teacher and I'm sure he/she will come up with a solution.

just tell him hey can we just talk after class because I need to do my work and you are distracting me. you dont need to tell him he smells or needs a shower. thats rude and childish. if you cant stand to be next to him. talk to your teacher. or when he talks simple dont look up and dont answer or even acknoledge him that way eventually he will learn to not talk to you when you are working.
