I was shelving some books in non fiction, or listening to an excellent Strong Towns Podcast, depending how you want to prioritize it. I finished the shelving part at least and wheeled my cart back along ranks of people on Internet computers. A large man with gray hair and a full beard caught my eye. He looked almost like he could be a biker. He was a tough looking man! I saw his screen as I rolled towards the staff elevator. Two librarians were standing around at the reference desk.
"Just a heads up." I said. "There's a big man- gray hair, full beard, out at the Internet computers. I saw his screen over his shoulder."
"Yes?" One of the librarians said.
"He's looking at videos of kittens."
