The times they are a-changing in ways even Bob Dylan didn’t foresee.
I have an early childhood memory riding my bike and coming across a discarded booklet on proper social etiquette. It had the perfunctory rules. Gentlemen always open doors for ladies. Stand when a lady comes in the room. And so on. But the one that I remember vividly is this: A lady always extends her hand first in greeting. Why? Fifty years ago I could understand the concept, but even then, I thought it was a bit much. Today that rule’s been abandoned.
