The Tricksy Beaver

The beaver proposed building a dam on  the creek, but the creatures who dwelled on the bank naturally demurred.

The beaver then returned with a new proposal.  He would place sticks and logs in the stream so that if a creature fell in, it might find something to cling to.  This safety measure, he averred, if done properly, might even offer an easy way to cross the waters.

He received their assent.

Unaccountably, after he had installed his safety measure-cum-transport option, the creek flooded.

Oh my, the beaver said.  I will have to add more safety measures, they are needed now more than ever.
