Analysis of Dear John

Goodbye my John, my one-legged friend.
We spent such a short time together, but you met your end.
No longer will I hear the sounds, the chirp and sputter.
That I used to hear, from the bottom of the caged gutter.
You sat there still, unable to flinch.
You were powerless, as small as a finch.
Bound under the sun and grass, next to the macaw.
We give our sincerity, and welcome you to your Shangri La.
