“It’s impossible for a woman to lay it on too thick with a man. If you tell a man he’s eight feet tall and say it often enough, with your eyes wide and a throb in your voice, he’ll start stooping to go through seven-foot doors.”

Context: “Growth is a good thing, up to about seven feet tall, then it starts to get inconvenient.  People eight feet tall bang their heads, their backs ache, their circulation slows, they spend more for food and clothes, and when they fall it really hurts.  Who can they make love to? ---The same is true of cities.  After a certain size they get more frustrating than exciting: People collide and anger turns to crime.  Streets become dangerous, housing costs more, tax rates rise, schools teach less, structures dwarf people, air smells stale, water fouls and traffic slows no matter how wide the roads.”
