Well it depends on how i'm feeling if it is half full or half empty.. sometimes you can only see negative and sometimes i'm really overjoyed so it depends on that haha:P
lol when i was young (5 years) a woman asked me what the difference was, and i said: well mathematical there isn't any difference 8-) weird me haha
I'm a realist. It's half both. Heck yeah. Anyway, I see things how they are, although I do get depressed, which skews my opinion. I still say half both.
If you start with a full glass then empty out half of it, I would call it half empty. But if you start with an empty glass and fill it halfway, I would call it half full.
A realist. I do the same, but on a shaky ground (like when I have no knowledge of the - history of the glass), I will assume it is half empty, because I am that negative. (and why would someone fill a glass half, and then let it be? Makes more sense someone has taken a sip from it already.)
Half-full; I'm a pessimist and I would slap anyone who says it is half-empty regardless of their outlook on life for the simple fact that they sound retarded.
