How do I tell my parents I'm adopted?

You need a new hobby. :)

This is a stupid question as parents know if they have adopted their child before the child does unless it's a older child adoption in which case the child is aware of what's going on.

First of all, how do you know your adopted, and I think your parents would know unless you would switched at birth, in which case you should get a blood sample just to be sure. If you found out and are worried that your parents didn't want you to know, then they'll get over it. They must've known they couldn't hide this from you for forever.

How on God's Green Earth would your PARENTS not know that you are adopted??? Your mother would have given birth to you. You're just the black sheep of the family, not adopted.

Wait until it's your birthday, then jump out of the cake holding a sign that says "I'm adopted!" Preferably with a smiley on the end :D

How could you possibly be adopted and your parents don't know? That makes no sense at all.

Thats actually the dumbest **** Ive ever heard obviously your not adopted. i highly doubt you know what that means ..

Congratulations! You're officially a terrible troll!

Start with "mum, you know what the internet is, right? How about 'a troll'?"

just tell them.. get it all out at once,, it will be better once they know..
