I fell off of my electric skateboard today and I got a dime sized cut on my elbow. I went to the doctors and got stitches. I didn't tell my parents and I don't think I will any time soon either.
Why don't you want to tell your parents about your injury?
I think that if my parents find out they might not allow me to use it anymore and I just want to keep having fun on it.
Just tell them what happened to you. There is no need to hide it, part of skateboarding is falling and they will find out eventually.
Whatever, I don't agree. I'm going to keep using the skateboard and not tell my parents.
If they find out without you telling them, they might want you to not use it, because you are keeping secrets. Be upfront about it, and they could let you keep using it.
