U R So Lost

OK, seriously, I was walking along a street when this young foreign woman approached me (Swedish perhaps) and asked if I knew where number 318 of the street we were on was. I spent the next 60 seconds discussing the ins and outs of the possibilities with her - whether it was up or down the street, what angle the moon currently was in the sky, what colour socks she wore to little school, etc, when finally I asked her what shop it was she was after. "Apple" something-or-other was the name of it. And what did it sell? GPS equipment.

I'd walked 10 paces away from her before the irony of it dawned upon me...
