““Billy stayed in the wagon when it reached the slaughterhouse, sunning himself. The others went looking for souvenirs. Later on in life, the Tralfamadorians would advise Billy to concentrate on the happy moments of his life, and to ignore the unhappy ones—to stare only at pretty things as eternity failed to go by. If this sort of selectivity had been possible for Billy, he might have chosen as his happiest moment his sundrenched snooze in the back of the wagon.””
