This time, however, it was more of an american experience, considering I was attending a conference organised by a US vendor. Pure work, hardly enjoyed the city from a fruitman point of view, even though taking the tube continues to be fascinating. It's just always amazing to see so many people dressed in suits in the tube.
The best professor I had at LSE, Ian Angell, used to say that observing people in the tube was a fascinating experience. That's why he changed from maths to social sciences. Could be, though I don't think you automatically understand people better by walking into social sciences. Just like you will never be a good writer by studying literature.
