I don't know what was going on yesterday. People on the roads were behaving oddly. This could be one of those weeks. There are periods when people, almost as a group, appear to act very crazy. I think that we humans are not consciously aware of how affected we are by season changes. Yet, here I am again, talking about something I've noticed around the time the weather starts to change at the tail end of winter. There are three incidents to mention just from one car journey home yesterday. I was pretty pissed off at lunchtime too, when I went to buy some more plaster in Farnborough - I think that was because I was parking in an unfamiliar car park, with poor signage and a sense of low-council-investment all around me.

Anyway, the incidents are:

• A suited man in a cheap Citroen, seeing a line of traffic ahead of him (and it wasn't that bad) suddenly losing his rag and giving his steering wheel a damn good whack
• A driver that didn't like it when I pulled in front of him, despite the fact that I'd been indicating for about 15 seconds, was in the outside lane, and well within my rights to do so - he waved at me as though to suggest I was mental - this made me wonder whether my left-hand indicator was actually working (had it not been, then I would have looked mental)
• The driver who refused to allow me to pull into the lefthand lane - despite the fact that I needed to, in order to stay on the road, and couldn't go any faster, since a car had just pulled out in front of me, thus limiting my speed. I had my indicator on, and rather than let me pull in, this car chose to undertake me. I hooted my horn at him for about 45 seconds. I was very angry. It still makes me angry.

The message to take away from this is that there was a lot of road rage about yesterday. Maybe it is seasonal. Maybe there are just some real dickhead on the road.

Maybe I'm one of them.
