Yesterday, I ran into a whole sequence of medievalists among the stacks at the main library on campus. While talking in a low voice to one of them, a library worker reshelving books came over and asked us to be quiet since even quiet voices carry far. After all I'd put up with this summer, it rankled a little bit, but it was fair. I was in a library after all, meant to be a place of quiet study.
Today I was back in the same library, and none other than the woman who had shushed me yesterday was busy working there too. Only this time, she was working with someone else, and they were talking in normal tones of voice as they wandered back and forth past me, chatting away. And this time, it made be really irritated, since only yesterday this very same woman had asked me to be quiet for the same offense. Although annoyed, annoyed more for the hypocrisy of the situation than the actual offense, the same logic floating through my head all summer still seemed to apply. She needed to talk to her co-worker to do her work. And so I said nothing. After all, if she remembered me from yesterday, she might take it as a vindictive act.
Should I have asked her to be quiet? Should I have been asking everyone all summer to be quiet? Personally, I'd like to feel I can have the odd quiet conversation in a library when I run into a friend. But neither would it have been appropriate (I suspect), much as it was the loudest thing in my summer of loud libraries, to have asked the floor polisher to do it some other time.
