Usually when people find out you do the telephone reference thing they axe you what whacky questions you have answered. I'm generally stumped because I forget about most calls after I answer them unless they've been particually interesting or especially hellish. Like say someone calls for information about Steinbeck, I'll remember that. Conversely I will also remember a call if someone calls me an asshole and hangs up.
I was just thinking after a call that the type of patron, beside our pantheon of steady wackos, that calls with the hardest and most obscure questions are little old ladies. I swear, if you get a call from a curious octogenerator you will have five books open on your desk and one of your co-workers doing a furious google search and the other checking online resources. But the payoff is worth the struggle. Old southern ladies say thank you like no one else in the world.
