I remember one car journey to Cornwall especially well. The M4 motorway was having its yearly resurfacing in the middle of the school holidays. We had been driving forever with the caravan on the back of the car and the road was narrowing to 2 lanes, from 3.

Dad was driving and was in the middle lane, carefully letting in the last car beside him, when from no where, a driver tried to push in front out of turn.
With the grace of a mechanic who know the ability of his machinery, Dad, accelerated forward blocking the road and with the window down, yelled, “Eat Cone, dickhead.”
I’ll never forget that.
