Trinity

Optimist and Pessimist sat across the table, Eyes locked over a glass of water.
Pessimist, "This glass, is half empty"
Optimist, "Well, if you look at it another way, it's half full"
Thirsty came and drank the water.

Lessons: Many.
To not theorize, you must be thirsty.

Life becomes good or bad, when you have too much time to think about it.

Sitting across the table, discussing endlessly, is one of the joys of friendship.

Believer and Non-Believer, both are same in that they only have theories. Only the one who has drunk the water, can tell you what it tastes like.

Comparison, can give the false perception, of an absolute which doesn't exist, often mistaken to be reality.

Without difference, communication would be impossible. Mind can only measure difference (This also comes from this book)

Good friends, can become enemies, over ideological divisions, each suffering thereby.

Past, Present and Future, are connected by the water in glass, as life in body.

Pessimist projects from the past (the glass had to be empty first), Optimist projects from the future, and both iterate in relative realities.

I am not thirsty :) and if was, I would have preferred Coke, at this hour. But yes, I have a glass of water on my table now, and I sure will drink it.
