When I was around 8 years old, my family was in the backyard making barbeque on the grill. My brother accidentally touched it and burned himself, but I didn't believe him and thought he was faking it, so I also put my hand on the grill

Needless to say I burned myself and my mother told me to help my own stupid ass.
I was in a toy store once, and there was a skateboard in one of the aisles, so I got on it and tried to ride it. I immediately regretted it because I lost my balance, and stood there trying to find something to grab onto for like 10 seconds, all while trying not to fall off the skateboard. I fell off it and scraped my elbow and made a ****load of noise
And finally, last Summer I was in our garage, and put my hand onto the wall to balance myself as I was stepping over something. I put my hand on an open wire or something and it sparked and I got a huge ass blister on my right hand in the space between my thumb and pointer finger. It hurt like **** to try to write anything after that.
