Special days

On the second day, I visited the American school. At first I was surprised at the size of the school, the numerousness of the student. All the American students spoke one's opinion during a class positively. I thought that we should have followed the aggressiveness. One difference between American students and Japanese students is American students have good boy and girl relation. Why is there such difference? Is it a difference of the culture?
When we take a photograph in Japan, we do a peace sign. I was surprised that they did not do peace sign in America.
My buddy was a girl. Her name is Samantha. I was tense very much at first. She talked to me willingly. On the coattails of her, I was able to be relaxed. The difference of the language made our communication difficult. I felt a lack of English some other time.
For one day that it spent with her and other friends, it was early that time was over very fun. So, at the time of parting, I was lonely. It was a special day for me.
