Today my business partner has been wandering round the office wearing waterproof overtrousers.
I asked him at lunchtime why he would do that, given that he'd spent the whole day inside (apart from a wander out to empty his bin, although even that was under cover).
He told me that it's cold at 7am and gave me a look that conveyed, with succinctness and sincerity, that this was perfectly acceptable behaviour and no further questions should be asked.
The overtrousers are still in place.
I worry that one day this will all seem normal.
