Answer:
One of the most important Greek Laws of custom was called xenia (xenia) which was the giving of hospitality. Even though Ancient Greece was divided up into many different provinces that had their own laws and customs, xenia was the only one that was accepted by all of them. Xenia dictated that if a stranger came to your door you should feed him, bathe him, clothe him and give him a bed for the night; only then could you ask who he was. He could stay as long as he wanted, and when it was time to leave, the guest and host would exchange gifts and tell each their friends of the persons deeds, either if they had been a good host or if the guest had told them stories of personal adventure.
