And then she figured out the whole situation in, maybe, ten minutes, just by watching my face across the dinner table. I didn't say more than ten words—‘Pass the tortillas.' I don't know how my face conveyed that information, or what kind of internal wiring in my grandmother's mind enabled her to accomplish this incredible feat. To condense fact from the vapor of nuance."
