Dr. Mehta, to whom I had wired from Southampton, called at about eight o'clock the same evening. He gave me a hearty greeting. He smiled at my being in flannels. As we were talking, I casually picked up his top-hat, and trying to see how smooth it was, passed my hand over it the wrong way and disturbed the fur. Dr. Mehta looked somewhat angrily at what I was doing and stopped me. But the mischief had been done. The incident was a warning for the future. This was my first lesson in European etiquette, into the details of which Dr. Mehta humourously initiated me. 'Do not touch other people's things,' he said. 'Do not ask questions as we usually do in India on first acquaintance; do not talk loudly; never address people as 'sir' whilst speaking to them as we do in India; only servants and subordinates address their masters that way.' And so on and so forth. He also told me that it was very expensive to live in a hotel and recommended that I should live with a private family. We deferred consideration of the matter until Monday.
