I know that feeling, got cut up by what i thought was a punk ass kid in a shitty little car, he was driving like a knob under taking etc etc because i beat him off the lights going into a lane merge, he undertook me and pulled out into a closing gap forcing me to slam on the anchors, i gave him a blasting of the horn followed by a finger salute shortly before pulling up beside him a traffic lights and realising it was my sons cadet instructor who had just left the same place as us, i wasnt to bothered but my lad was doing his best to shrink into the seat and hide behind the B pillar
