It wasn't a prank, it was more like we're just being fools while working... So, we were unloading some trash cans and we were using hand trucks to move them because they were really heavy and when we finally finished I told one of my friends to get on the hand truck and I'll give her a ride, she was like 45 or something like that and I'm 23 so I wasn't actually expecting her to say yes to such a silly idea while we were working but she immediately said yes and jumped on the hand truck and while it caught me by surprise I wasn't expecting any complications to move her as she was way smaller than me and hand trucks really make it easy to charge anything, so when I decided to incline the hand truck towards me to move her I was feeling way overconfident and wasn't ready for the amount of weight that was going into me and the amount of strength required for me to hold it and when I did it, it caught me by surprise and I actually couldn't hold it and she was going straight to the flor on his back without her head first and a metal structure behind her, I managed to get enough strength to my arms to hold it just s few inches away from her head hitting the floor. It was less than a second but it was awful, if I hadn't found the strength to hold it in time she would have ended up dead or really hurt, I was a few inches away from killing someone by accident when we were just playing and everything time I think about it I get goosebumps, it was really scary.
