A new apartment building is going up on our block, and the sidewalks are closed on that side of the block. "Oh well," I told my wife, "we'll just have to...wait, I swear there's a phrase for traversing the other three sides of the square instead of just taking the straight-line route, but I'm not coming up with it..."
Am I crazy, or is there a phrase for taking a route like this around a square?
