this is very interesting. Mabye there won't be a follow up fml to this one, but I would definitely like to know the outcome of the story. just remember your parents love you, even if you may be a mutant ;) (I would also explore the possibility of mutant powers..it'll kill time until you learn the truth)

it is possible, actually.

FIRST of ALL you are 100% correct. If one parent is blood type A she's either AA or AO; blood type O is OO (if you don't know this, sign up for a course in biology). Using a punnet square as proof (look it up.) you'll see the only blood types you, if a legitimate offspring, could acquire is type A or type O. But seriously take this as a chance for adventure!!! You're current "parents" have raise you, definitely well enough to know that if their blood type is A and O you can't be B, so now find your real parents A side plus is that for finding out you're their real child, they'll compensate the years they haven't raised you with gifts gifts gifts =D assuming your parents took the wrong baby home at the hospital. By hey be careful, the case might be that your dad cheated, you're mom's type A, so genetically, it couldn't have been her. But if you're dad hooked up with a type B woman then I guess it's up to you whether or not to keep it a secret =/

Have you ever tried to fly? You should have a go at it, your parents didn't tell you you came from another planet to protect you. BTW, who gives a shit how you got here, you're here so make the best of it. Why do people always make a huge drama when they find out they are adopted?

freak a

It's Like Bioshock

Or a missing child

lol ithink ur a mutant

This is the most interesting way of finding out you are either adopted or a love child.

Orrrrr your genetic code is just irregular. Could be the case at hand here.
