Spring SAD beginning

As ever, Toronto's change from abnormally cold spring to incipient summer happens almost overnight: 10C on Tuesday, 20C on Thursday, and getting up to the mid20s for the the next week at least. This after I put clean flannel sheets on both beds barely a week ago. Ah well. The lows will be cool enough for a while, and I shall simply shed a few of my sleep layers in the meantime, starting with the flannel lounge pants.
