One day, a coworker said to me (having no clue what he was about to inspire), “I tried that, but nothing happened.”
“That’s impossible,” I replied.
When I started my reply, I simply couldn’t believe that the suggested approach wouldn’t have yielded any change. But by the time I finished, I realized I was stating a fact: It’s not possible for nothing to happen. The instant nothing happens, it ceases to be nothing and becomes something.
I pondered for a moment and then explained this to my coworkers. This launched into a now infamous series of discussions about nothing.
