If you’d watched the video then you’d realise these aren’t “pupils”, this is a guy with a lot of experience in the sport passing on tips and help to the local kids at the skatepark. That is exactly how people used to learn this sport before it being mainstream and how a lot of people still do I’m sure. He is more than able to give kids help and they will appreciate it a shit load coming from someone obviously good at the sport.

Also the goal in skating is never to “not hurt yourself”, sure ideally you don’t want to hurt yourself but it is a sport that when learning you are inevitably going to hurt yourself and you need to accept that. On the whole your take is pretty shitty man.
