American Sign Language of Prophecy

Brushing crumbs off your chest can be reversed into the ASL sign for “happy” by brushing up instead of down. If you always make a practice of making your last crumb-brush in an upward direction, you will be telling all deaf people in your line of sight that you are happy. And, I propose that this will make you actually become happy in some sort of self-fulfilling prophecy kind of way. It might also make you less concerned about the crumbs that always end up on the front of your shirt.
