Second good deed of the day, ish.
Came back via a long traffic strewn bit of road and passed a couple of cyclists, mainly lit ok. Then came up to another who's rear light was a bit crap, I could only pick out ninja. Anyway, said bike has a child seat on with a kid on board.
Dad mode kicks in.
Pulled alongside the rider (my million watt system on) and said 'excuse me, not being rude or anything, but I can't see your rear light' (best posh voice from a Manchester Lycra lout). Got a garbled excuse about a bracket being loose yadda yadda (it wasn't). Then I said "well I am just concerned".
Where kids are involved... I can't let that go. he wasn't some yob either.
