【单选题】

Some people are lucky enough to be born with a good sense of direction and even if they have only visited a place once, they will be able to find it again years later. I am one of those unfortunate people who have an extremely poor sense of direction and I may have visited a place time after time, but I still manage to get lost on my way there.

If anyone ever asks me the way somewhere, I always tell them that I am a stranger to the town in order to avoid causing trouble, but even this can have unpleasant results.

However, at this point, I decided it was too late to turn back and search him out of the crowd behind me as I had and appointment to keep at the office with a new client and I did not want to keep him waiting. Imagine my situation when my secretary showed in the very man who had asked for directions to my office and his astonishment when he recognized me as the person he had asked!
