They are called birdies. Like humans they have goals and work to do. They wake up early, stretch out their wings and fly to the nearest gathering station. The station produces little pictures with quotes on them. It can be small words of wisdom, or simple statements. They are cheerful and optimistic. The birdies get one each before they fly to their target. One birdie for every house. Like Santa coming down the pipe, they come down with the pictures hanging from their beaks. Every morning humans wake up to a new picture. It might be: You are so much better than you think, or that they are allowed an extra treat during the day. Never the same message, and always appreciated.
Birdies, we love you
