I was on my way to work yesterday at about 06:30-ish. This being the
time of year it is, it was dark but the roads round here are pretty
clear until about 07:30, so it's an ill wind and all that...
Pulled up behind a white builder's van at some traffic lights. The
Drivers door opens, the driver jumps out and trotted around the rear
of the van towards me.
I definitely didn't remember using sign language on anyone this
morning - I very rarely do, being ancient and placid. OTOH, some
people go mental if you just look at them crosseyed.
Turned out ok: No vicious blow between the eyes was forthcoming.
He just wanted to know where he could get a rear light like mine
(LD600) because "You can see it from miles off". I told him, he
thanked me, jumped back in his van and we went on our way.
Unexpected!
