A new library patron approaches me at the front desk of the library. They tell me that they have moved from a nearby library system and now live in this system. They would like a library card. I explain how this is all going to work and then tell them it is a good thing they moved, because our system is four percent better than their old system.
"Oh." This patron responds. "What makes you four percent better?"
"It is hard to quantify." I reply. "But mostly it has to do with how much more sassy our staff is than theirs."
