It's a windy day. The garbage can blew away, and mom and dad sent their son to get it and bring it home. But it's still windy, so that's not an easy job. But he keeps at it, no matter how difficult his task is made.
Sisyphus was condemned to roll a rock up a hill, only to watch it roll back down, for eternity. I hope this child is not still out there trying to bring the garbage can home. -via Metafilter
