I was coming home from the football today doing about 80 on the M621 when I recognised the number plate of the car in front as being that of a colleague, so I started to overtake and as I drew alongside him I started to blare my horn and wave at him, he just looked at me as though I was demented, which in hindsight I probably am The least I should have done was to raise my inner sun visor so he had a chance of recognizing me, oh well no doubt I'll see him at work and explain, or maybe I would be better denying everything.
