The caged bird

The door to the cage was opened.
But the bird that spent its past 5 years in the cage did not know what to do.
The master prodded the cage and asked it to fly away.
But the bird hesitated, unsure of the future.
It's time to leave the comfort zone, he says.
Was it gratitude, sadness, or anxiety that was stirred up in the bird's mind?
Casting the last glance back, the bird wonders if its clipped wings can really bring it far.
