I am enjoying this feeling of vitality, calm, and peace.

Nobody photographs an ordinary Tuesday afternoon, which is why the surviving record of any life over-represents both the crises and the parties.

Calm has that difficulty generally. It registers as an absence rather than an event, so it can run for an entire afternoon without once being noticed, let alone enjoyed. Bad hours announce themselves loudly. Good ones just quietly happen and go unlogged.

Enjoying it is an actual act rather than a mood — turning round at four o'clock and registering that right now nothing is wrong, before it shifts and you look back and realise it had been fine for hours.
