One day, in second grade, my teacher had the class do one of those "write about what your father does for a living" things. My father was an architect. So, I just pointed out the obvious, added a first-hand observation, and scribbled an illustration.
Everyone laughed. They said, "Architects won't fall down if they don't design buildings."
But, as a seven-year-old insider on the profession, I knew better. I was pretty sure my father would fall down if he didn't design buildings.
