When I was a teenager I felt very vulnerable without a coat or jacket, though I didn’t really understand what was going on - I just kept one on by default in public. I can remember walking across campus in a long, thick black coat in summer and not being consciously bothered by the heat because it wouldn’t occur to me to do otherwise. I’m sure it looked like a very affected mannerism to anyone who wasn’t around when I took the coat off to reveal the random assortment of clobber I’d pulled out the drawer that morning (Mr Spock-shirt and school trousers, most likely).

It wasn’t until a couple of years later in a pub when someone asked “why don’t you take your coat off?” that I actually considered the question and had a sudden flash of clarity - I didn’t actually have to live that way, it was just a sad old habit with ideas above its station. I didn’t run straight out to buy a bunch of jogging shorts and sleeveless vests, but I got better.

Of course I never wore a balaclava, that’d be mental.
