Where do angels come from?

The University of London... at the Regent's Square underground stop near the university, I stepped off the train and took the elevator up. It stops about fifty steps below street level. I stood at the bottom of those steps like a statue. I had just lost most of the strength in my arms due to disease and my legs have never been good. The larger consideration was the huge suitcase I was carting around the UK for a month. The luggage had gotten bigger by the mile. ... Out of the elevator poured another load of people and I was in the way. One of the students coming out looked at me, smiled and grabbed the bag. Without a word he lifted it to his shoulder and urged me up the steps. I had the thought that he could be a thief making off with my earthly goods, but it was for nothing. He set the suitcase down at the top of the steps and wished me a good day, Then, he was gone off to the school. I had a "Who was that masked man?" - Lone Ranger - moment and then wheeled the case toward the British Museum and our hotel. We meet these people everywhere we go.
