How does the hero bring together his experiences from his
adventure and his old life back home?

The Hero's Journey are the steps that a mythical hero must take in order to complete the path to their purpose. There is no pain-free path… and it must be “chosen sacrifice” if it is to lead you towards self belief.

in our power to make a world happy - to teach mankind the art of being so - to a character hitherto unknown - and to have, as it were, a new creation intrusted to our hands, are honors that command reflection, and can neither be too highly estimated,

i would just say something like,

i need to go outside owner to pee, hold on owner let me mark this tree. i'm thirsty now "starts drinking water" now i am tired. what are you eating owner can i have some, you can't refuse my cute puppy eyes.

just make sure you write that in your own words that way you don't get in trouble.
