Life changing travel

How can travel change your life? There's bound to be a hundred exotic and interesting ways.

I was compelled to volunteer help to a group of Americans going clockwise round the Northern Line when they really wanted to be going anticlockwise. I not actually convinced that they were all that happy about being helped but I blame all those New Yorkers that just came over and helped Mum and I when we were there.

The Northern Line isn't really a clockwise/anticlockwise line either. But the bit that I normally use works that way. And you have to wonder whether giving someone the sort of directions I normally manage to give is a kindness at all.
