What should I do?

Ok. So please keep in mind that I am kinda shy, get good grades and am polite around teachers. I'm also in the 6th grade. My teacher said that we'd be switching seats soon but I can't take it anymore. I'm sandwiched between a kid that kicks the back of my chair and another kid that smells really bad and is REALLY gross. I've told the kangaroo to stop kicking my chair several times but he obviously has some problems and won't stop. I don't know what to do about the boy that smells bad. I can't tell him to take a shower. LOL I really don't want to ask the teacher to move me because then everybody would ask me why I moved seats and be nosy, I just like to blend in. :) Any suggestions?
