why dog, why?

everything is still and calm, i wait for my love to make it home, the dog is on my chest falling asleep slowly, his eyes close eventually with a little eyelash flicker. shortly, i will be surrounded by lots of drunk people and loud rock music, alcoholic drink in my hand to take the edge off. sweetness. now if only i could get this dog to not pee on my rug whenevr i leave, everything would be cool. but at least he is sweet while i'm around. evil when left to his lonesome. why must he piss on my rug at the foot of my bed? why?
