Classic etiquette never gets old for me...
Here is a little excerpt from Emily Post
original chapter on greetings.
Oh how I love a good white glove reference!SHAKING HANDSGentlemen always shake hands when they are
introduced to each other. Ladies rarely do so with gentlemen who are introduced
to them; but they usually shake hands with other ladies, if they are standing
near together. All people who know each other, unless merely passing by, shake
hands when they meet.
A gentleman on the street never shakes
hands with a lady without first removing his right glove. But at the opera, or
at a ball, or if he is usher at a wedding, he keeps his glove on.
