Question: What ever happened to "wash behind your ears"? When I was young, this was a universal (if old-fashioned even then?) instruction to ensure physical, and moral, cleanliness. Now, like quicksand, it has fallen out of the discourse. Why?
Wasn't it usually (in fiction anyway) a caution to boys? The ones rolling around playing sandlot baseball or milking cows and bathing once a week, who would need to be reminded of the dirt they couldn't see in a mirror.
