He who digs a pit will fall into it,
and a serpent will bite him who breaks through a wall.
He who quarries stones is hurt by them,
and he who splits logs is endangered by them.
Carpenters hit their thumbs with hammers more often than me even though they're better at striking nails. When you roll with hammer-men, you're bound to get hammered; when you roll with burglars, you're bound to be burgled.
