Maybe the glass is niether half-full nor half-empty. Maybe the glass is twice as big as it needs to be.

But if as you are suggesting, the glass is a 2 pint pot, an containing 1 pint, it is stil half full/empty.

is the glass half empty or half full? Well, my awnser is..... stuff the glass and take the bottle!

i would have to say that it depends what you are drinking, if you want some more and how much it costs.
