A glimpse into another world

I just got a video call notification from iChat which I accepted. Up on my screen appeared a young American guy called Trevor  who I didn't know. He didn't have sound turned up on his laptop and couldn't hear me but I could hear them talking about me. He turned the camera around and I could see a number of people in some sort of classroom situation.

He may never get back in touch and I may never know who he was (they were).
