That's the sound my forehead makes when it meets Stone's elbow in the middle of the night.
Nothing like being roused from dreamland with an elbow to the face.
At least Stone woke up too and told me how sorry he was....
....the last time I woke Stone up with my elbow to his face, I let the dog take the blame.
Oh the joys of two 'tosser and turners' sharing a bed.
