would you say a glass of water is half full or half empty?...i have come up with...if your filling it, its half full, and if your drinking it its half empty...but then if i think about it more, I can see that it can also be the otherway around...? what would you say?
btw, saw a joke somewehre
a pessimist will see it as half empty, an optimist will see it as half full, and an engineer will see it has built twice the size it needs to be
