Looking outside the window

I went to Yokohama with him to see my friends from university. We don't see each other very often. It was the first time to  see them in three years. But when we meet it doesn't feel like for so long. I guess it's always like that with close friends.

On the way there, he was looking outside from the window and he made friends with a little boy sitting behind us. He peeked through the gap between the seat and the window and they both chuckled. They kept doing it until we get to the station where we got off. I took this photo just before he found his friend.
