When Henry came into Billy's life, he gave all his attention and energy to him and as a result became an inseparable part of Billy's life.
The unconditional love that Henry had for Billy only grew as time passed. He showered love on him when he used to return from school, played with him at the park, chased jackrabbits in Sierra Nevada. It was during these chases Billy came to realise the hunting skills of Henry. Henry then helped Billy in overcoming the racist school bullying and by being a reliable partner in running treks.
In this heart-warming account of Henry's time with Billy, we come across many such occasions when the bond between a human and his best friend is experienced.
