I'm glad to see this topic come up, this knowledge is sorely lacking in today's world. Along with walking on the "street side" of a lady when your on the sidewalk...things like that. This stuff is not taught anymore, that I know of....and it's a shame, really.
Amen! Other lost courtesies include opening doors for ladies, helping a lady into and out of the car, helping a lady into and out of her coat, pulling the chair to seat a lady at the table, rising when a lady enters or leaves, etc. And there are even special rules of etiquette for those of us who have wives with very long hair.

I daresay that almost no one knows these courtesies any more, and will give you strange looks if you exercise them. But on the rare occasion that a woman recognizes the courtesy and expresses her appreciation, it's worth it.
