This is it, right now. It's just coming up to midnight and all is deathly quiet.
I have vacillated over the years between being a lark and an owl. Unusually I can live with both (though not at the same time!) Either very early in the morning or late at night the place is quiet and stuff gets done. During the day I find I rarely get stints of time long enough to have a good run at a task. It's not, I want to stress, that I don't like people(!) it's just that very rarely do I get much time to myself and so such time is precious...
