i voted once a week or so. it's closer to the "or so".
if we go out to eat, we almost always order a dessert. you only live once (this time around), so you might as well go from soup to nuts, and back to dessert again, lol.
it's also the only time i drink coffee. i'll get a double espresso to go with the little "dulce". many desserts can be too sweet, so the bitter coffee sets a background to cut through and balance it.
at home, we only have a proper dessert; that which is served within a short time after dinner, on special occasions, or if dw or i pick up something we've been craving and had the opportunity.
now, i have a late snack, something sweet, or salty, or both almost every night.
