Speech in a primary school in the US

In October, I had a speech in a primary school in Salt Lake City, Utah. Because I visited there on my trip, I had a chance to give this speech. When I entered the classroom at the time, there were 60 kids in a room. I talked about the history between the US and Japan, and I talked about friendship between them and me. They listened to my speech earnestly, although my speech is not neccesarily joyful. So I was very glad to have become friends with them.
