Knowing that they'll probably stale within a few days and therefore go to waste unless they're finished, you find yourself at the half-dozen cookie mark within a few hours. (Finally, you decide that you'd be better off just finishing the whole box immediately to get them out of the house so they'll stop tempting you.)
