Respond to the 1st story

I watched the 1st video. I can't understand all because of my low english skill but it was very interesting and I was impressed by it.
I think the filmmaker want to show us that if we have the different background, we can get aling well with people. We don't must judge people by their nationality or background.
At first, a white boy seems prejudiced against a black boy and he didn't try to make friends with him. Far from it, he try to fight him. However, they laughed together all too soon. I think it is difficult for us to understand people who have a different nationality or background from us, but judgeing a person by one's background is not good. I want to judge a person without seeing their nationality or background. Then we can make friends with people all over the world.
