If there's a better way to spend Christmas than reading the newest Aaronovitch. I've yet to find it. Many thanks to incandescens for this particular treat. (It's been *two years* since Foxglove Summer . Where does the time go?) The s-i-l posted this graph on FB. Coincidentally, coworker gave me Santa Claus patterned rubber-soled socks for Xmas. Of course I was delighted.
