Purple

 Today at lunch I walked past some Red Cross volunteers and one said to me: "Miss, if you and I ran around in circles we would look like purple.  Do you want to try it?"  Although I passed without saying anything I laughed really hard a half a block later.  Glad to know my blue dress was appreciated!
