When Keri was a little girl, my mom said that she got off the bus one day and was very sad because all the kids had a nickname but her. And the bus driver would say hi to each kid's nickname ("Hi Moose, Hi Crazy-Hat", etc.)
So my mom said, "you have a nickname! Keri IS your nickname!"
And Keri got so excited and she beamed and asked, "but then what is my real name?"
And my mom said, "Carrot."
