It's a good thing I don't work at the library... I think it would wear out my patience faster than a classroom of children. Certain people remain clueless about not using cell phones within the library... and then there are the old people who are clueless about computers, the volume of their voices, and many other things... and then there are those who take it upon themselves to remind people of the rules but in a less than uncivil manner... the messiness of ordinary life.
