I love the way DFW makes these small, minute observations of life that always seem to make me go "yeaaaah I can relate too!"
We need a word for that, in English. I had a very close friend that had an uncanny ability to find things about any situation that I would gloss over, but when he pointed it out, I would realize that I had missed seeing it but I completely agreed with it. And, weirdly, this friend also committed suicide.
