The Nights start Drawing in now

I can never quite remember when midsummers day is, due to its habit of skipping around days when I think it should always be on the 21st. According to the internet it is today - or rather tonight. Does that mean that today is the longest day and tonight the shortest night? Or is that yesterday? The nights start drawing in now. That slow-quick creep to autumn, then winter, then spring. That endless circle - or rather spiral. Days creeping backward and forward like tides. The sun is shining out there, and for once it does feel like midsummer. There's always something more other midsummer than winter, something a bit more unsettling about it all - the height of the surreal lengthening of light, particularly when you go outside an hour or so after night - 10:30pm say, and still see a vague trace of light in the sky.
