dogs are the loneliest people I know

there is this yellow lab
at the corner on my walk
he is there everyday barking
there is a big shaggy white dog
behind the fence with the lab
I toss them biscuit pieces
the lab barks all the time
his eyes are empty
he has lost the reason why
but he still barks
the white dog waits and watches
he barks because the lab barks
it use to be fun but now
it's the only thing they do
behind the fence
