The Unfinished House
A builder started a house but ran out of stone. He sent for more and waited.
The quarry was slow. Weeks passed. Rain came. The unfinished walls crumbled.
A builder down the road had a rule: if materials didn't arrive in ten days, he covered the unfinished work and moved to another project. He returned when materials came.
His houses took longer to complete but didn't crumble while waiting.
