We ended up fighting for the chair and he jumped on it and then I tried to get it by jumping on him and forcing him out but instead we spun around and around. I ended up falling off and was so dizzy that I stumbled and hit the fire plays head first and got a big old goose egg!
I learned not to jump on a spinny chair, let alone with another person on it. I had a big ole goose egg on my head for 5 hours and thankfully my mom was not home to yell at
