Someone already said it... darn. The glass is twice as large as it needs to be. I always loved that
Also... I only read half the posts here because I'm friggin tired right now and ready to go to sleep, but... whether the glass is half empty or half full is circumstantial, period. It is
not mathematical. Has this already been mentioned? Who knows. ::shrugs:: ::yawns::
Allow me to explain.
If the glass starts out empty, and then is filled up halfway, then it is half full.
If the glass is filled to the top, it is full. Then, if from there half of it is poured out, it becomes half empty. There, simple.
EDIT: Ok, ok, fine, it is mathematical... but the importance here is that the state of the glass's fullness/emptiness is based on circumstance.
