Technically, there IS only one answer. It's both. If some thing is half (50%) of something it must be half (50%) of something else, since there are only two options it must be half full AND half empty.
Stop looking at wikipedia! Shit is bad for you, DONT TRUST IT! Anways my glass is half full. I got a plan and workin hard. Im going to the top. You need money in this world more than ever these days. Why not make alot? hehe
uhhh if my measurements are correct, it is 7/17 full. some asshole took a sip while I was taking a leak.
actualy it's needing to be refilled. although it's usually a cup. and seldom stays "half" anything. =^^= .../\...
As a scientist, I'm an eternal optimist in practice, a pessimist in expectation, because most experiments will likely not lead to a favorable result, but through persistance you may stumble on something useful, yet I doubt it.
