Time

All my adult life, infact even as a child, I've been obsessed with the strange uneven nature of time. How it goes slowly, speeds up, stops, races away. Supposedly it is a constant in our world, but my experience of time is it contains the ultimate variability. From afar, in space, looking down, what can explain two days not that far apart in "time" when two people can have such different conversations. Day One: "I'm free for a while, do you want to get together." Answer: "yes, of course." Day Two, a bit later, according to the calendar. Same question. Answer: "no." The "of course" this time is implied.
