Read the passage from part 1 of “to build a fire.”

as for lunch, he pressed his hand against the protruding bundle under his jacket. it was also under his shirt, wrapped up in a handkerchief and lying against the naked skin. it was the only way to keep the biscuits from freezing. he smiled agreeably to himself as he thought of those biscuits, each cut open and sopped in bacon grease, and each enclosing a generous slice of fried bacon.

what does the man’s reaction reveal about him?

his desire to share with others
his willingness to take risks
his joy in simple pleasures
his tendency to hide the truth
