How do I know for sure?

Get a knife from the kitchen, slice it into your arm deeply, if red fluid comes out you're just a normal pre-teen that thinks the world revolves around you because your parents shelter you.

Be sure to cut horizontally though, if you go vertical you'll see first hand just how mortal you really are.

And after that awesome response from Skullbie, I'll lock the thread. Can't get better than that.

Hotcakes, we discuss serious issues in this part of the forum.
