The last was chronologically the first to hit my brain, though the storyline of today runs 1->2->3. I've left out the causal chain (or progression of ideas, if you like), but a bit of detective work might figure it out, if you're curious.
I wonder if, in the interest of accuracy, I should reproduce that last link at the top, to start off as well. Fascinated at having started the day on that theme, wandered about, then come right back to it through a different door. Or window, perhaps.
Definitely heavy on the theme of echoes / co-incidence, today. Just a record.
