Expect me to fly?

"My life was like a little bird
In a cage,
When I was not allowed to go outside,
I filled in with rage.

When I started growing up,
Years passed, time flied,
I few times tried to break free,
When I failed, I cried.

One day, They opened the cage,
Telling me to go, fly high,
I was flabbergasted and
Confused but I tried.

Always been locked in a cage,
Dreaming about the huge sky,
Just getting me out of the cage,
Do u really expect me to fly?"
