One day after visiting a modern factory, a group of retired people were whispering something among themselves. When asked, they were shy to say it loud, but one person was brave enough and asked: "What chemicals are you using to make the floor so shiny?" That was their main concern after seeing a vast engineering miracle. I knew that they were inspired by what they had seen, but this was the question they were interested in the most after the tour, full of a lot of new information. And my role was to provide them with the answer :) John Mason Brown was an American drama critic and author.
