Mea culpa. Today I was a moron.
This morning I ran a red light.
No excuse, but I was just following everybody else. I didn’t see it changing until it was too late to stop.
It’s in a spot where there’s another light (which I did stop at) which is ahead of any conflicting traffic, so there was no actual danger.
Still, I made a mistake, and I’ll be more careful in future.
(The guy behind me, who caught up later, could hardly criticise. He was on the phone the whole time.)
