One day in second grade, my teacher obliged us kids to 'write about what your fathers did for a living.' My father was an architect, and I figured all the other kids would already know what an architect did. So in addition to pointing out the obvious, my scrawling provided a few first-hand observations and 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. It sure looked to me like my father would fall down if he didn't design buildings.
