You don't walk up to my parents and say 'Hey I'm an atheist' ! Instead when they ask you 'Its Friday...go change your clothes and cleanup because the Azan will be in around an hour's time', you say 'What...? I'm not going to do yoga 5 times a day....besides there isn't anyone up there' ! And then you get smacked by your Mom with her saying 'I'm going to slap you if you ever say anything like that again' ! But naturally I did ! :P And yes my friends knew because I was pretty darn vocal with them ! And jeeez dude, this is 'atheism' we're talking about not 'Hey I'm Gay and I'm coming out' ! Not everyone gets a hissy fit when you tell them that you don't really believe in these things anymore.
