They fly up in the sky!
Birds have wings, which allows them to fly.
On the other hand (or other wing if you like to put it that way) I don’t have wings because I’m a human, not a bird 🙂
And this is the reason behind the invention of airplanes by humans, to be able to reach the skies and go beyond the boundaries of this world.
And honestly speaking, the unique ability to just spread up their wings and fly away to distant lands and pastures of the birds makes me a little envy sometimes.
Because in those sometimes, I wish for having a pair of wings and flying away from all that tangles me into the ground.
Which is something many also wish for!
