My wife says I’m a glass half empty kinda guy while she prefers to see the glass half full.
To illustrate, someone recently asked me to answer to the question “What would our life be like after we move to a new planet?” to which I replied:
“Life would be alien in the sense that we cannot survive on another planet within reach (AKA our solar system) without never going out of doors and breathing the air. We’d be depressed because we’d never see the light of the sun and breathe the air.”
Although I’m convinced this is the correct view, my wife says I’m just like my father was – a pessimist. I admit to it proudly if not pessimistically.
