HIKING ON P.E. CLASS

Hello! I post a couple of pictures of today´s trip on P.E., so that you can download them. I have got two questions, and I wondered whether you could answer them.
First question: Who is the boy behind Andrea?
Second (and most important) question: What is he doing????

I have got another picture. I have called it " The loneliness of a football star", but I accept suggestions. Don´t hesitate to post your comments!
