I'm going to tell kids to move so I can skate
Why do you want them to move?
They are annoying the shit out of me!
It is okay to want to be able to skate but you do not own the street and cannot tell others what to do. They have rights too and deserve to use the street too. You will be called a bully.
I don't care, I'm going to do it anyway
People in your community are not going to appreciate your behaviour. Probably they'll prefer to keep distance from you. You should go some other place that have designated skating area.
