I am always an empty pessimistic guy obviously. I always ask what the glass is half full of? Does it matter if it is full of let’s say water when I want a delicious beer? Some may want water you can be happy with water sometimes. But I want a tasty beer preferably full as well.
If someone handed you a half full glass of anything you would feel ripped off. I hate over simplified arguements. Again pessimist and over analyzer in me.
