How can i tell my dad?

I am so sorry and they probably would disown you i am in now doubt i am not sure how old these parents are? you knw its sad because i would gladly accept you and him. i am from the 50's and i tell you what it does not matter what you want in life you are suppose to be happy and if that is what makes you happy i think its fine. i am not sure if i would tell them now or ever. i know alot of peple do and they regret it. but once you are sure of yourself and can deal with lsoe of parents do it. i mean 18 is old enough to knwo what you want but if you are going to colelge i would keepit tight with me. i am sorry to hear this and wish you all the luck and stuff in the world.
