a thousand sandwiches
mom's comment reminds me of a game paul and i play called a thousand sandwiches. it's dead simple and good for long car trips.
you just describe a fine sandwich, in graphic detail.
"sourdough roll, crusty but not so hard that it bruises your palate when you bite into it, just sliced straight across. breast of roast chicken, sliced, but it needs to have the skin taken off and it should have been roasted with lemon zest and garlic butter. one perfect slice of tomato -- if the tomatoes aren't good, cancel the entire sandwich. a thin scrim of homemade mayonnaise. a sprinkling of crunchy sea salt applied directly to the tomato, and freshly ground black pepper over the whole affair. warm the whole thing very gently in the microwave. sorta mash it down, slice it in half, devour."
and then the next person does it. "you know that flexible afghani flatbread with little bits of onion in it? take some of that..."
