Numpty day today, the numpty being me!
Started off by getting a bike out of the shed mid morning for the later ride in, faffed around the house for a while then got dressed for the commute including shoes and overshoes to counteract the windchill only to realise as I got on the bike that I had automatically put on clipless shoes when the bike I'd got out was the only one in the fleet with flat pedals. Couldn't be bothered to change.
Then on the way home, the cheap Chinese front light with freshly charged batteries stopped working about 4 miles from home. No back-up light as I rarely use this bike and 1 1/2 miles of the remaining bit was on an unlit "quiet lane" which was interesting!. Still can't get the light to work so it's gone in the bin.
