"Hospitality is always an act that benefits the host even more than the guest. The concept of hospitality arose in ancient times when the reciprocity was easier to see: in nomadic cultures, the food and shelter one gave to a stranger yesterday is the food and shelter one hopes to receive from a stranger tomorrow. By offering hospitality, one participates in the endless reweaving of a social fabric on which all can depend-thus the gift of sustenance for the guest becomes a gift of hope for the host."
