The other day I wrote about grad students can always see a glass as half-empty. I've been thinking about that and wish to emend my statement. First of all, it should be specific to doctoral students. Masters students are usually pretty perky, at least until the end when they get antsy to find a job. Second, they just don't find the glass to be half-empty.
No, the glass is half-empty, and the water is dirty, but they don't want water anyway, and half a glass isn't enough, and the glass looks like it might have a crack in it, and why is there no lemon, and it's lukewarm, and they would rather have it poured by someone else.
