Leche does not know how it came to be, just that it is here and it is alive. She knows that the best things in the world is a good warm glass of milk and a nice plate of freshly baked cookies to go alongside it. He knows that these things make him feel warm and cozy inside, and he wishes to share the comfortable feeling to others as well. They'll keep their friends company, even strangers, as they believe that a stranger is a just a friend they have yet to get closer to.
