A wee glint in his eye.......

This is another of those days when nothing blippable seemed to leap out at me, so fell back on 'old faithful'.
Tonight, out of the corner of my eye, I realised that Dimairt was sitting really still, waiting for me to throw a ball for him.
He was half asleep waiting for me to finish answering some e mails.
He had only just a slit of an eye open, hoping for some action.
How could I let him down?
