India is built on levels. I am stumbling over little ledges and uneven stairs, every day. I am slow to learn that a walk across a floor or a sidewalk or a road does not assume the surface will be smooth.

After three weeks, I am more cautious. I expect a few challenges as I move about. I accept the stubbed toe with less frustration over the different-to-me architecture and remind myself to lift my feet higher or move more carefully than I do in my familiar homeland. I try to do less charging around and to be more observant. I remember that I am the visitor. And in the dark, I take the arm of my son, whose eyes are better than mine and whose steps are less practised in stubborn habit.

There is a metaphor here for the traveler, I suppose. A lesson for me, at least.
