You wander the snack aisle of the town convenience store—your last stop on your list of errands. You needed to pick up more granola bars among other things. Dash ate your last one. You look at the options available. You both liked the honey flavor oats, but she did mention wanting to try honey-hay bars. You pull a box of hay bars off the shelf and toss them in your basket. She did eat eight of the ten bars in the last box. You grab another for good measure before heading to the dairy aisle.
