Chapter twelve could be titled “The Lawns of Summer”. It is another interception of Leo’s story which re-focuses on the Spaulding family. Douglas’ grandfather begins the day, happily reveling in the sound of the lawn mower running on their lawn, an indicator to him that summer has truly begun. Grandma, however, tells him that Bill Forrester, the man cutting their grass, is planning to plant new grass on their lawn that will only grow to a certain height, thus eliminating the need for lawn mowers. (Note: no such grass actually exists yet in the real world) Horrified at this, Grandpa gives Bill a firm lecture on how little things can matter more than the big ones, especially to experienced people like him. Bill attempts to change his mind, but only convinces Grandpa further of his position when he learns that the new grass will kill off the dandelions.
Grandpa finally pays Bill the cost of the grass flats in return for him not installing the flats in his lawn. He takes a nap and wakes up in the afternoon to find Bill cutting the lawn again, having learned to appreciate the “little things,” thanks to Grandpa.
