During childhood I spent a lot of time in San Francisco. Venturing to the Top of the Mark, and then at the Fairmont hotel, I learned about the city from a bird's eye view.
My father took me for what were then called booster shots. We walked to the pediatrician's office. These little mounds occurred at the corners of the doctor's building. I have called them boosters ever since.
Notice how you made connections with words and creativity when young.
Consider your own booster story.
