From the One City Over Public Library, where I am doing my 'student librarian-ing':
I was 'observing the reference desk' i.e. chatting with the two reference assistants, one of whom looks kind of like a rabbi to me--he has a serious countenance and a very impressive beard--yesterday evening. About 20 minutes before closing, a girl about eleven or twelve, walking by with her family, darted up to the desk and said, "Excuse me: Sir, I love your beard!" and then darted away again.
