What is Home, Home is What

What makes a home a home? It isn't the bricks and mortar, so what is it? Is it the objects, the smell, the feeling of comfort? And, is home even a specific place? Do we not sleep equally well in a hotel or a tent? Could home not be a feeling in itself? Is home a place, or is it comfort and security? And, do all homes provide comfort and security? What does home mean to you?
