Who are you?
I don't know how obvious it is, but I will talk to and take friend requests from anybody. I already have issues with names - one guy will tell you I could never remember his name in person, but even he doesn't know we had been Facebook friends for a couple weeks before I connected Dave the person with Dave the name. (It doesn't help that his profile picture isn't is face.)
So: Who are you? How's it going? What do you like doing? Why do birds suddenly appear when you are near? And anything else you'd like to add.
