Thank You for Taking Your Medication

You find a box in the attic.

This box contains prescription bottles labeled Happy Pills™ (Other-Directed). The instructions state that one should take a pill every eight hours and no more than three pills in a twenty-four hour period.

Swallowing one of the large tablets has no discernible effect on the user. However, those who make eye contact with that person will experience bliss and contentment for as long as eye contact is maintained or until eight hours after the last pill was swallowed, whichever comes first.
