A dog likes to sleep.
A dog likes to change where a dog likes to sleep.
A dog likes to get his head in a comfortable position, especially tucked underneath something.
A dog likes to lie in doorways.
What a dog does not like is someone, aka Misery Mistress, pointing a camera in his face every time he tries to find a new peaceful position.
Just because you have finally bought some new batteries and a new charger for the camera does not mean you should keep sticking it in my face.
So go away mistress and let sleeping Pippa lie.
