You’re driving and it’s dark and it’s raining.nAnd you’re on the edge of the city and you’ve been driving all night.nAnd you took a turn back there but now you’re not sure it was the right turn.nBut somehow it looks familiar so you just keep driving.nHello. Excuse me.nCan you tell me where I am?nnYou’ve been on this road before.nYou can read the signs.nYou can feel your way.nYou can do this in your sleep.
