If you wou'd have Guests merry with your cheer, Be so your self, or so at least appear

Be not niggardly of what costs thee nothing, as courtesy, counsel, & countenance.

Fish and visitors stink after three days.

Fish and guests stink in three days

Tart words make no friends; a spoonful or honey will catch more flies than a gallon of vinegar

If you would be revenged of your enemy, govern yourself.
