Pawprints

A trail of pawprints in the snow
Is just enough to let me know
That life contains another layer
Of which I am not a player.

What takes place when I'm away
Or fast asleep in dreamland's sway
Means not that I am gladly missed, 
But more like I do not exist.

The creatures of the night and I
Can co-survive and this is why -
It's easy to let something be
When what it is you do not see.
