Thomas's post brought back some memories...
When I was a kid, I lived in Anaheim Ca. We had a mutt named Finneas J Houndigger; Finny for short. I'd attempt to sneak home at 3 AM, loaded, past the old man's room and up the stairs to mine. Finny would wake and start barking like Dino in the Flintstones.
One night I was not home and the Police came looking for me. They came into the house- the door was unlocked. Finny slept soundly. Not a peep. "This is the Police- is anyone home?" Finny slept soundly. My parents woke and dealt with the Police. Finny slept soundly, waking finally just as the Officers left.
And why shouldn't he sleep? He knew even unconscious this was no business of his- the sound of footsteps were not munk's....
