those people who make life miserable for those coming out do it because they're jealous it's the people that know you that you listen to not some girl in your class who thinks she the 'it' girl.if the people who know and love you seem to have a problem with it,you can ask them to explain what they do/don't like.if you keep thinking the way you do,you'll never be able to be yourself.if you change before going out,who's being double standardy? (if there's such a word).just be yourself and if some people can't handle it,they should sod off.

and anyways give them a chance to see the other you and place judgement not you assuming they'll think in a certain way and not giving the new you a chance.
