Billy was inspiring because he smiled all the time.
Billy was inspirational because he neer frowned.
Because he was grateful for everything.
The thing Billy couldn’t understand was why all the able bodied people were so miserable. Why did they need him (with his crutches, his chair, his white cane, his smile smile smile…didn’t they already have everything?) It was Billy’s service dog, a Labrador named Gus who knew the answer but Gus couldn’t talk. Still, our narrator is omniscient. Gus saw able bodied people were missing a soul ingredient—something essential to life like Vitamin B12. Gus the Labrador knew without B12 people or dogs develop rickets.
The able bodied people had spirit rickets because they were missing an element called “here and now”. Gus the Labrador knew Billy didn’t need to smile so much. Being disabled he already had the prize.
