This is where it started:
As the twig is bent, so grows the tree — but you cannot bend an oak into a maple.

After a little more contemplation, he added:
An oak tree is considered an epitome of mightiness and dignity. It stands on its own terms, casting shade and acorns as nature intended.
It may be unfair of me to put it this way, but a maple tree is … a sap donor.
Maybe “donor” in the sense of “having a hole drilled into your trunk and then having your vital fluids removed.” Synonym: “taxpayer.” No wonder Washington is always telling us to get bent.
