You have a nice day, too

OK, I'm a total library nerd and as such, I find the catalog far too interesting and too much fun. When I get the chance to show somebody how it really works, I am probably a bit more excited than the occasion warrants. Sometimes, people get into it, too. Most of the time, I get the "Drop the Bone, Dog" look eventually. And sometimes I get the nice woman yesterday, who seemed interested enough about my on-the-spot tutorial, and complemented the system by cheerfully predicting the imminent redundancy of librarians.
