Things that Go On in a Library

     I was just standing by the elevator that goes from the second floor of the library (where my office is) to the first floor (where the technical services work room is) with a cart full of books that had to be withdrawn because the cleaning crew got floor wax all over them. Anyway, as I was waiting, perusing a soon-to-be-withdrawn book, two students came down the hall and stopped briefly by the elevator. The one turns to the other and says, "An elevator?  When did they put that in?" I remarked, as calmly as possible "It's been here over ten years now."  Student says to friend, "I think I'll take the stairs."

 . . . which have also been here for over ten years. How long this student has been unobservant, I couldn't guess. Oh well.
