Driving with my wife to a christening in the NorthWest, above Manchester... My directions said to turn left on High Steet. And no street signs to be found anywhere.
We came to a large intersection with a stop light, so I figured it MIGHT be High Street, I turned left and asked my wife, "would you spot a street sign so we can be sure we're on the High Street?"
After a few seconds she confirmed, "Yes this is the High Street". I didn't see any signs and said, "How do you know?"
And she said, "Because the house numbers are getting higher"
Now she's been here for a long time, like naturalized long time, and she has a BA degree too. So I can't imagine what it's like for tourists and new arrivals...
