I love to skateboard. Have you ever ridden one?
Yes I have! Im not very good at it though! I cant do any cool tricks on a skateboard! Can you?
I am just learning so only a few
Oh okay, yeah I see the parks around where I live but Im scared to do the ramps and things. Skate parks have been around since the 1970's, mostly skateboarders and BMX bikers use them though
Ya, I remember seeing them growing up and being so terrified about them. 
Yeah, I read that it can be controversial in some areas where people have damaged curbs, stoneworks, steps, benches, parks and plazas!
I personally do mostly flat ground skatboarding and try to not damage things
Yeah of course, you have to be respectful. The first skateboards were made with wooden boxes with roller skates wheels attached to the bottom!
