The face is not a secondary billboard for our internal feelings. It is an equal partner in the emotional process.
It's amazing how pervasive food is. Every second commercial is for food. Every second TV episode takes place around a meal. In the city, you can't go ten feet without seeing or smelling a restaurant. There are 20 foot high hamburgers up on billboards. I am acutely aware of food, and its omnipresence is astounding.
I think that I shall never see a billboard lovely as a tree. Perhaps, unless the billboards fall, I'll never see a tree at all.
