Why?Who?What?

Woof Woof
Bark Bark
Did you know that life,
is really dark?
This poem is a lesson,
Most people don't care,
About the message,
Many people are crying,
I remember 4 of my dogs dying,
I'm trying to stay steady,
Because I'm not ready,
It is very hard,
I have went too far,
It is just life,
Hold on tight.
This is the end of the song,
No more fights,
May the birds sing,
Even the ones with broken wings
