When the old man waved first, and offered the faintest of smiles, I knew we'd made progress in making Puerto Cayo, Ecuador our home. I begin almost every day with a one-hour walk from our home into town and back. And every day, without fail, I see the same local people, going to the same places in their own morning routine. In the beginning, the Puerto Cayans weren't unfriendly at all. They just didn't seem overly friendly.
