I always wanted a nickname, but my mother would never allow anyone to call me anything other than Jennifer. If someone tried to call me Jenny, she would draw herself up as high as her 5' 2" frame would allow and say "My daughter is not a donkey!"
Then about eight years ago my best friend started calling me Jennerator because I got things done. I loved it! I finally had a nickname. After she died I put JENNR8R on my license plate in her memory.
