Is a kite (麻鷹) free?

I saw a beautiful kite (麻鷹) flying leisurely over the typhoon shelter in Causeway Bay this afternoon, seemingly without a care in the world. In reality, of course, it was just circling again and again, trying to catch a fish like the egret.

So, what was going on in the mind of the kite? Was it enjoying the freedom, being able to fly anywhere it wants, whenever it wants, to see anything from higher above everybody else?

Or was it actually grumbling that it was condemned to fly in circles all day, trying to catch the same old smelly fish again and again?

Is freedom just a matter of the state of the mind? Can we really be free in spite of our surroundings?
