half/half

Well, we've all heard the age old question, "Is the glass half empty or, is it half full?"
Recently, someone told me that they have the "perfect" answer to that question. They said "If you are pouring the drink, it's half full. If you are drinking the drink, it's half empty." That's a really good answer. Honestly, I cannot even remember who told me that...but if it was one of you, thanks, but I always hated that question anyway. The whole "optimist"/"pessimist" thing is just not me. I don't consider myself either. I am a realist. Meaning, I don't care if the glass is half empty or half full. All I care about is how much juice that kid just wasted and that I have to, now, clean the glass.


So, tell me now...which is which???
