Silence is golden. I never understood the phrase as a child, teenager, or young adult. It seemed like a common phrase that was used a lot, or maybe I just talked too much. Maybe it was a prize at the end of the silent game. Now I like that game as a parent. Only if I could get my four year old to understand how to play.
I think the first time I understood the phrase was when I first became a teacher. After all students were dismissed, there was total silence. The chaos of the day disappeared in minutes, and we were left to be able to think and plan again for the next day. Ah, yes.
