You are lesbian and your parents think you are going through a phase What do you do?

Be intelligent, and explain to them in a very rational manner that you're attracted to women and not men. Don't get frustrated when they don't understand-sometimes people just can't understand. Just keep cool, and explain everything possible, and keep it casual-don't treat it like a big deal because quite frankly it isn't. They'll probably understand whe you (hopefully) find love you want to spend the rest of your life with.
