Skateboarding seem like fun, but it looks really painful when you fall.
Yes, it is! Specifically in skateparks which have been around since the 1970s. A lot fo aggressive skaters go there.
And I hate when I am walking my dog and skater come directly to where I am walking and only change direction at the last second.
Yeah sometimes skaters ride and perform tricks on the sidewalk. I bet Tony Hawk does that.
