there are mainly three types of people that you will meet in your every day life. pessimist, optimist and "don't care".
Two guys, one a pessimist and the other an eternal optimist, had been friends for years. The optimist was always trying to get his pal to see the bright side of things.
The optimist found a dog that could walk on water. This is perfect, he thought. There's no way that cynic can say anything negative about this.
He took his friend duck hunting so he could see the dog in action. Mid-morning, they finally downed a bird. It fell on the other side of the lake, so the optimist sent the dog to retrieve it. The animal trotted across the water, grabbed the duck in his mouth and ran back.
"Isn't that amazing?"
"Hmmph," the cynic said. "That dog can't swim, can it?"
