Whew! It turns out I have not forgotten everything I know about working in a public library.
I spent this afternoon filling in at the information desk at one of our library branches and had a good time in spite of my anxiety. When I reported this to my husband, he observed, "It must be a bit like looking after grandchildren".
I know what he means. I was a bit out of practice, but I did have fun with the patrons. And at the end of the day I got to send them home.
