Half

The optimist thinks the glass is half full, while the pessimist thinks the glass is half empty.
Me, I drink everything out of a shot glass, and the bartender is always around to slide more my way, or he leaves the bottle there and we settle up the tab at the end of the week.
It doesn’t matter if the bottle’s half-full or half-empty either. The bartender keeps more in back, and his distributor runs an all-night liquor store a block away.
One time, all the shot glasses were in the dishwasher.
Except for the one in my pocket.
Cheers!
