There are some of us who will never learn 'how to get around' one's city. We lack a head for sense of direction, for memorising landmarks etc. We can try all our life, and we'll only cope, but never be comfy.

Of course, if I'm just going to commute to the office and come back, I could do it blindfolded, and those days it's easy to be without the phone. It's exactly when you're doing something unusual that the phone is so handy.
