I had my hair cut yesterday.   The salon was quiet.  No sound except the background radio and the snip of scissors.

After about 20 minutes one of the hairdressers said “You can tell when we’re enjoying our work, we don’t talk.”

“That’s true,” said mine, “When you really get into it, you just concentrate on what you’re doing, you forget to chat.”

Concentrated silence.   That’s what flow sounds like.

How often do you hear it in your workplace?
