Qualified Written Request How Might I Go About Friending Him On Facebook...?

How might I go about friending him on facebook...? - qualified written request

I recently discovered one of the actors in my favorite music on Facebook. I met him briefly the other day. I know that we can hardly be a friend, but I think it's a very cool, cold, and the person that I really add on Facebook. If I get a message with your friend request, what is the best, what to write, to persuade him to accept my friend request?

Thank you!
