I think I'd easily be able to convince people that my goal in life is to go by with as little sleep as is humanly possible... It's 9:20PM, I just had coffee and you can bet I'll be up until midnight. I must be insane. LOL!
No worries, I know I can't possibly be the first person to come up with a story like this - there must be dozens like that around, it's easy to start off in the same direction with a kid discovering their super powers.
I had a 14 year old kid discovering he had heat vision during a chemistry class and subsequently thinking he was a mutant (lol!). He then finds out he's Superman's son and obviously assumes it means his Mom had had an affair with the superhero, until Dad does his spin-thing and... well, jaw drops and please call 911 cause it gets so crazy starting then that this kid is going to need serious psychiatric help. Hehehe!
(and I've written it in the first person as well.)
I'm just saying I'm getting a sense déjà-vu -- I'm not offering that as proof of anything whatsoever. Like I said, no worries.
Of course, if you start going into the whole "kid is adopted and was born in an alternate reality", I'll really be scratching my head, cause that would mean we don't *think alike*, we actually *share a brain*. LOL!
