Roller skates and violent movies

Liam, James and I were talking about what is wrong with children watching violent movies. Luna is very sensitive and could not handle watching Lassie on one of our family movie nights but Liam is less sensitive. He told us about a time he watched a violent movie with Byron at Grandma's and didn't like it but watched it anyway. We talked about ways he could walk away and not watch it and he says...

"When I am wearing my roller skates and I see a violent movie I use my brakes and stop. Cuz there's brakes in the front and the back."
