OK, so we’ve all learned that an 8-by-11-inch box of cereal is definitely not filled to the brim: “This product is sold by weight, not volume.” Prior to this disclaimer, I experienced one disappointment after another. Now I know enough to expect half a box of cereal and half a bag of chips.

I accept the possibility that it’s some sort of turn screw inside my tube of lipsticks that actually allows for only half a tube of lipstick.
