A popular online social network site allows one to express a thought as well as display pictures on a 'wall.' Friends can add their comments to the wall or choose to 'like' what they see. The dialogue below between three friends is fueled by a composite of various situations one might encounter working at a library, real or imagined.
Friend 1: I'm going to the library today
Friend 2: Like
Friend 3: I go to the library often and browse the fiction shelves and look through the DVD collection. There is something special I'm trying to find.
#1: Today I want to renew a DVD. It has a whole year of episodes of a TV show my mom watched when she was a teenager. I have one more disc to see, but I've renewed it 2 times already.
#3: Isn't that the limit?
#1: Yes, but maybe if no one else wants it I can get it again.
#3: What's the name of the show?
#3: Hey, that's the one I"m trying to find.
#1: I didn't think anyone else wanted it. I'll return it tonight.
