Whot does being free means? Being not in the prison? Be able to fly away from your problems? Does it mean you can go whereever you wish?
Who are really free in their rights? I belive that is a bird. Just come to think of it; birds have wings and don't have documents of place where they must be their whole life.
For example, birds can steal food right out of turist's hands and they will never be cought and punished. They can travel without tickets, tney don't need money to be happy.
That is real life they have, not as ours. We live our long life-time working from 8am till 8pm, and we think that we we are good. Building our career and later where's no time for living left.
Birds would probably laugh their belly off...
