Example 3: The afternoon sun was low in the western sky and golden-red light spilled across the perfectly mown lawns. Each leaf on each tree fairly glowed with healthy vigor. It was so perfect it looked like a photo from an advertising brochure. Much better than my previous visit. Gorgeous, in fact. I was filled with envy. Nothing would do except to beg, borrow, or steal enough money to buy a house in the neighborhood. And I happened to know that one was available right across the street from where I was parked.
