Patience

The Message of this video is to have patience. By getting upset over something that already happened isn't going to change what just happened it probably would make things worse.
This video is shot at the end of the day because the filmaker wanted us to see that the older man had been working on the cement and he was almost finished. And by the boy walking though the entire sidewalk you would think he would be furious. But all the little boy wanted to do is see what he was doing and say hi.
