Old Dog – Young Dog
Two dogs are trotting down the road, one an old dog, the other a young dog.
A butterfly flits across the road in front of them.
The old dog glances at the butterfly and keeps on trotting down the road, wisely knowing that he could never catch the butterfly. The young dog sprints forward, absolutely convinced that this time he can, indeed, catch the butterfly.
May both dogs live in you.
