The main thing I can say is that I wrote cringeworthy fanfiction. I know, it's ridiculously common. I wrote this Pokemon/Sonic/Zelda crossover, too. Like, 4 or 5 unfinished fics of it.
There was a piece of metal in the ashes of a fire pit in the backyard of my childhood home. The whole thing was still smoking. That should be enough to tell me it was hot, right? NOPE! I tried to pick it up and received burns on my thumb and forefinger for my stupidity.
My sisters and I used to play Pokemon trainers and we'd wander around our backyard having "adventures." The place where our yard stopped and the other house's yard began was separated by a fence; there were these trees growing alongside the fence in the other yard, not too tall. That area was Viridian Forest.
During the summer time, after being stung by yellow jackets and a dead bee (not sure if that would qualify as something stupid) one too many times, I took to killing them via plastic baseball bat. Pretty much every single day (save for Sunday) was spent smacking those bastards like they were baseballs. I thought that it would cut down on the number of them in the yard. I didn't realize that more could just come from elsewhere. Hard to tell their buddies not to go to that yard when they're dead. ...and they'd probably all come back for the sole purpose of stinging me, anyway.
I also had the bright idea of trying to take a cat for a walk.
