In search of a comma

I’ve started a list of things that are on loan to other people, because I am getting tired of waking up one morning and thinking, for example, “Hey, what happened to my copy of Eats, Shoots and Leaves?”

I know I loaned that to one of you, possibly Sean or Dianna, but I cannot remember who. I don’t need it back but I like to know where things are, so please let me know if you have my copy and I will jot you down on the list. And if you are extra-quick in telling me you have it, I will put a little happy stamp next to your name.
