Judging from the blogs I read, there’s a northern hemisphere heat wave this week. From Helsinki to Montreal to Tel Aviv, everyone’s writing about how hot it is. Only, one person’s hot is another’s pleasant summer weather. Here it’s about 27 degrees celsius, and Petersburgers are wilting. I happen to think it’s quite lovely when compared with Washington’s 35-degree, 100% humidity summers (to which I am going to subject myself in a few short weeks).
