Getting into the festive spirit, wife putting up christmas decorations, discovers a bulb has blown on the tree lights, so I volunteer to drive to Asda to get replacement, Travelling back I waited patiently while a plonker in front of me in a Polo made up his mind to go, a bit further along I actually let a Taxi out of a side road in front of me, and then I slowed down and let a bus pull out from a bus stop, what is happening? is it middle age setting in? what can I do to prevent it?
