Sleep Well - Lament I wrote. Thoughts? Opinions?

This was written back in 2004 immediately after a euthanasia at the vet hospital where I worked. The vet there at the time pet the animal one last time and whispered "Sleep Well, darling". The words began flowing into my head, and out came this:

Sleep well my darling, you've earned your rest

you played your part and did your best.

There's no more trials, and no more tests.

Relax, enjoy your sleeping.

For night is coming near

and the ending of this story

the sun is westering

see the last flames of its glory

All was calm, and all was still

upon this solemn morning

The sun did rise with shuttered eyes

and your troubles died aborning.

For night is coming near

and the ending of this story.

The sun is westering,

feel the last flames of its glory.

For night shall come unto us all

a sweet and secret lover

and we shall claim that dark embrace

and then seek for no other.

For night is coming near

and the ending of this story

The sun is westering

free the last flames of its glory.
