You notice a girl in the corner of the library. Shes reading a couple books and writing down notes. You want to say hello to her but she seems to be too focused on her book. "I'll just talk to her when she gets done." You think to yourself. After a couple minutes she stands up and walks to the librarian to check out her books. Suddenly she trips and falls flat on her face. You can't help but giggle a little bit but you feel a little bad for her. What do you do?
