ABSTRACT
Imagine an across-the-fence conversation between two neighbors. Leaning through the white pickets (why not?), Elwood starts it off:
“My your yard is green, Harvey.” “Thank you, Elwood. Always nice to have a compliment. And may I say that
yours also looks fine.” “I appreciate the thought, Harvey. But as you can see, my lawn is not nearly
so carpetlike, so tightly woven with thatch, never a dandelion poking through. How do you do it?”
