How can I stop this really annoying boy in class calling me an emo or goth?

Erm I'm afraid I don't know how to stop him but you need to know that you can be yourself and if he calls you an emo just because your eyeliner is smudged a little (OR even if you were to wear emo style) that is your style and there's nothing wrong with it. Trouble is with many school kids they are attention seekers and that's what he's after. Just be happy with yourself don't worry about hing labels such as "emo" or "goth" and wear what you want and what fits you best! I hope things work out but just remember you don't spend that long with the boy it's only a few hours a day.
