It’s not just the sweat, though. The heat has been making me ratty. Normally, on my daily foot commute, I’m focused but cool and Zen-like, sort of like Patrick Swayze in Point Break, only during rush hour down Bishopsgate. But lately? Lately I’ve been uncharacteristically aggro, refusing to move an inch for oncoming gaggles of City boys and, on a few shameful occasions, deliberately stepping into their path at the last moment, colliding with a wet ‘squelch’ as I slop against their designer suits. Again, apologies.
