Believe a lot of people have seen skateboarding. Young people like to play very much, but they can only play well with more exercise, or they can fall easily. But I'd say, if a dog played skateboard more than you could, would you believe it? Aren't you better than a dog?
There's this guy who drove out the other day, and there's a guy on the street riding an electric car, and there's a dog! It's pretty clever to say that you're very skilled, not only to slide down and stand on top, but also to adjust your direction to avoid hitting the next car.
And the master's probably practicing skateboards with the dog. Because he couldn't keep up with the dog, he chose to train with the dog! I have to say, I really don't think I'm better than this dog. But the dog is good and the master has to be careful not to slip on the road, but it's dangerous at night.
