My mother equated day and night with common-sense.
She’d say, “It’s as clear as day and night that you did the wrong thing and should have done something that shows you have an ounce of sense about you.”
Our childhoods were taken up with her pointing out the folly of our innocence. We stayed out too long in the sun and suffered sunburn, but only once I have to say as bad sunburn is nothing to want to repeat.
At sundown, it was time to come in for in those days there wasn’t much in the way of street lighting and the few times we stayed out and tried to navigate our way home by the light of the moon resulted in us tripping over and scraping our knees.
They were great times; our lives governed by the rise and fall of the sun and our slowly acquired common sense.

My mother had essentially the same expression, but she only referenced the day (“clear as day…”) and not the night. I would sometimes counter with something snide, like “But, Mom, it’s cloudy out.” She rarely appreciated my retorts.
They didn’t when they were making a point.
I like these memories Michael. They’re nostalgic but comforting, like the main characters had a wonderful childhood and it shows. I did the terrible sunburn thing once too. Your right u don’t repeat that mistake.
Somethings we learn the hard way…
I didn’t like it when my mom warned me because subconsciously I knew that she was right and it almost like a prediction. When I was in first grade and went on a field trip to the countryside. My mom said, “Be careful of not to fall into the rice field.” You know what? It happened just like what she said. My shoes got all muddy and wet!
I liked that one…my mu if we feigned illness would say: “You’ll be alright once you get going.” I hated hearing it as I knew she was always right.
Haha… yes, she was!
