if you met a rock that was alive, what would you do?

I have a girl in my class, whom actually had an entire blog just of her own in the past. She comes in and tells me during snack time, "I just LOVE rocks so much. You know what I would do if I met a rock that was alive?! I would ask for its autograph!!" Then she proceeds to tell me the conversation she would have with the rock. It was just too funny; she is dead serious about her rocks. (I get rock gifts a lot.) I wish everyone could have been there.
