Optimists; can't live with them, can't shoot 'em. Luckily the world has darn few of them left. It seems the grind of life turns many optimists into pessimists in a damn hurry. Usually by the time they are 30 years old, their paper cup, having left glass years ago for the ease of throw away, is half empty.
I still got my half empty paper cup. I keep it in an old shoe box up in the closet right next to my unopened box of condoms I bought 3 years ago. At least something is still full.
There is a silver lining, though. I got a good deal on the condoms.
