I never got this question as a child. The first time someone asked me I thought it was a joke. I just looked at them and said "It's both, duh." I was a cheeky little thing sometimes! That's what I have always thought. It's both!!! Who came up with this test? Does anyone know? I still don't understand how a glass of water indicates how you view life.
Sorry guys but technically you are all wrong. The glass is full, half full of water and half full of the various gasses and particulate matter that makes up the air we breathe. It is not like there is a vacuum in half that glass ya know
As someone that appreciates a tall, cold bourbon and coke, if the glass appears to be half full I'd have to say it doesn't have enough ice in it but I'd still be optimistic that someone would come along and buy another round.
My boss just came up with a good one. As a former psychologist his response was, "The more important question is....what does your mother say about the glass?"
