American Style

I did not study anything during the break, but I did find one thing interesting in America since I came to U.S.A. I found that if people want to cross the street, they should push a button. When I first crossed the street in America, I waited long time, and  I thought that the red traffic light was too long. However,  a few minutes alter, I saw a young man came close to me , and then push a button. I was curious the reason why he had pushed the button, so I saw that button carefully. I  figure out that there was a word "Push" at the top of that button. Then, I understand that if person wants to crosse the street, the person should push the button, and after that, the traffic light will change. This is one of the interesting things that I have already known in America.
