An older woman came to ask about how she can donate her body to science. She was so upbeat, after I gave her the information she said "double high 5s my dear, and keep smiling!"
Then a woman walked up to the desk and said loudly with laughter, I need to know if I was born on a full moon. My friends say it would explain a lot. I looked up the date and told her... no, your birthdate did not fall on a full moon. (And I thought... what if it did? How would she respond?!).
Finally Mr. Purple Book walked by and asked the usual question-- is that the right time? and, oh, do you know where the hardback book is?
A woman who must have been new to the liberry heard the above three exchanges and was WOWed with what liberrians deal with on a daily basis.
