A few years ago, my daughter had pet rats. It was okay, because she was in college and they weren’t at my house. Then she asked me to watch them one summer when she went to Spain as part of the scholars program at her school. I found out how smart and friendly they were and used them to illustrate a funny story that I would send to my daughter in a series of emails. Basically, it was an excuse to photograph the rats and send funny emails to my baby girl. I don’t remember the story exactly, but it was about the rats calling her to find out when she would come home. They can’t wait, so they look up on the map to see where she was, set out to find her, have some adventures on the way like running with the bulls and seeing famous cave paintings and finally the welcome home party.
