Teaching Social Decorum in the US Air Force
"Arms off the table; Sit up straight; Don't talk with food in your mouth; Don't pick your teeth; Don't touch your face or your hair; Don't start before others; You're not a pig at the trough - converse and eat slowly; Don't slurp your soup; Ask people about themselves and don't talk about yourself; Look people in the eye and give a firm handshake; Don't bring up religion or politics, etc., etc." I have it all memorized.
Word to the wise: Please don't tell me about your kids. I only asked out of politeness, not interest. Tell me jokes and lies, be entertaining, and tell me something interesting.
