He would get up early, brave the elements, and he and his buddies would go hunting as soon as deer season began.
But this season he noticed that his scope no longer worked. It must have become damaged over the winter and he would need a new one. His buddies had a successful hunt, but he came home empty- handed. But at least they all had a good time with their camaraderie and good natured fun.

Finally it dawned on him. Maybe it was his eye that was the problem and not the scope.
