Last night's entertaining went off without a hitch. There's leftover pizza too!
Perhaps you're asking how does one judge the success or failure of a dinner? You can safely assume you've succeeded when your sister in law asks you to share recipes because they always like the foods they try at our house and your brother (devout carnivore) doesn't disagree! They left last night with writer's cramp and an armload of recipes.
I've often thought food speaks louder than leafleting and shouting.
