Talk does not cook rice.

Don't speak unless you can improve on the silence.

... all of us talk faster than we listen.

... even the most sublimely accomplished non-stop talker can't consistently please.

Have more than thou showest, Speak less than thou knowest.

Never speak loudly to one another unless the house is on fire.

People have to talk about something just to keep their voice boxes in working order, so they'll have good voice boxes in case there's ever anything really meaningful to say.

... talk, not sex, constitutes most of the intercourse between a man and his wife.
