My nickname was given to me by my grandmother's cousin during a trip to Portland, Oregon with my uncle. I was the designated driver. Everyone we were visiting had been retired for several years and they just couldn't believe how happy I was all the time. All of them called me Sunshine until the end of our visit. Using Sunshing just seemed a fitting tribute to relatives that took me to see Tillamook Rock.
By the way my real name is Judy.
