Answer and Explanation:
You forgot to say that this question is about the poem "Caged Bird".
The author shows how the free pass does not think about freedom, because this is something natural for it, that is, this is something that he lives normally and is present in its life at all times. In this case, the bird prefers to think of a relaxing breeze or fat worms so that it can eat.
The caged bird, on the other hand, thinks about freedom all the time and sings about it all the time, because it is something the bird longs for and does not have, but wants more than anything else.
