Dylan On Freedom

"No one is free, even the birds are chained to the sky.” - Bob Dylan

I think that this qoute that Bob Dylan had wrote is meaning or explaing its value of freedom. It's like saying everything and anything has its own limit. When he tells about the birds he saying they can only go up to the sky. No where higher or not even close to lower. Meaning like the ocean for example. They're not meant to be going down there. They have their own boundaries as such as we do. Like we can only take stuff up to its own limits. For an example we can talk all we want, for a number of time, but at the same time your not going to have the same amount of people listening as you did as when you had first started. If that even makes any sense. Another example is also being the audience. We can only take so much from one person until they start growing old on us.....
