Then there's continental drift, and there's the north Atlantic drift, there's snow drifts, and drift nets, and drifts of petals in the street after the Festival of the Flowers in Jersey. There's a copper drift that you can use to drive 2 pieces of metal apart without damaging either. like knocking a bearing off an axle, cos it had been knocking, and you had to take it off to replace it, if you get my drift!
