When I was in high school, I worked as a waitress, serving people who ate in their cars-the old curb service.
I was tiny at the time, barely 5" tall and weighed about 90 pounds, scurrying out there in the parking lot, so the cooks nicknamed me Mouse.
When I registered at kickas, I didn't really think I'd be staying around long; I just wanted a few questions answered. Because of that, I didn't bother to give my user name much thought.
Anyway, the name Mouse brings back mostly fond memories of my days as a curbie.
