umm :P difficulties ,it might be abit late but i can think of 3 things ,all kinda simple ,1 lie  fake it pretned ot be the nice duaghter/son they want ....i find this one easiest :( , 2 just be you ,if you dont wanna talk then dont talk just b yourself ,3 open up (probably the best choice) ik it sounds weird but parents have lived for a while and know at least a little bit ,and ik they probably cant help but just think if u had kids and they were doing what u were ,how would u feel as there parent? then act according to that

well if you have a boyfriend or girl friend depending on your Gender, then just basicly let them know but brake it to them as if they allready knew and then just laugh a bit more when your around your BF or GF, im in a relationship, and thats how i broke it to them and they've layed of me even tho im emo, anyway look at my BF's profile, search: AshMeakins, he's a really nice guy when you talk to him, anyway  good luck:)
