The casual

Light

   A fly

In the middle of the night

   A crow pecking at the window

  He wants his dog food treats

There's no rest for the weary

Say what you will

 I'm not telling you anything

You don't know

   You put on your yellow slacks 

Try the door

But it's still locked

They'll let you out 

One day

 And you'll see the sky

  And you'll call yer mom

   But she says 

  Who is this?

Just a crow 

Just a hungry crow
