It should be quite interesting, fly everywhere feel free, go wherever you want and be you flying wherever you want, feel a great connection with the sky and with the air to lift yourself as much as you can...
that children in the afternoon run to scare you or other nice people give you to eat to watch how you do it and then as you go in search of company or rest your wings at night and nest happy.
Thank you for reading :)
