Really, a lot of it comes down to good manners. Treat others the way you'd like to be treated. If you know how to carry on a conversation at a cocktail party, you'll do fine.
That said, it's useful to lay out these ground rules as you've done, because it's amazing how many people don't know how to carry on a conversation at a cocktail party!
I don't like cocktail parties, and I still know this stuff!
If I ever voyage to Sector ZZ9 Plural Z Alpha we'll have to get together for drinks.
Can't believe I mis-read your comment. D'oh. Well we can still have drinks but just not at a party.
Pan-galactic gargle blasters, I hope.
You have read The Hitchhiker's Guide to the Galaxy, right?
What a great series. Douglas Adams was a treasure.
How about his Dirk Gently books? Have you read those yet?
I have - at least the first one.
How did you feel about the BBC America interpretation?
Different, but hilarious. I introduced my library co-conspirator @Generikat to it, and she has not read the books, but also thought the show was funny.
