im from Australia too and (no offence to all cheerleaders out there) they really need to get a life. What is teasing u about stupid stuff gunna do? Just plain ignore them and if they keep on doing it, tell some teacher or ur parents. Dont feel like a dobber cause ur not, ur just sticking up for yourself. Ok, that probably made no sense whatsoever, but anyway. Dont feel down, ur not really overweigt!
