It's the 10-year anniversary of the 7/7 terrorist attacks on London's public transport system which left 52 people dead. I was not in NY after 9/11, but I was in London a few days after 7/7. I would never in a million years compare my experience to that of those lost and injured and their families and friends. I do remember feeling incredibly anxious before walking down into a tube station or as an iconic red double-decker bus would pass me on the street. Not to mention that I was a brown man with a beard in an age in which brown men with beard weren't exactly in fashion in the west. I was traveling alone and visiting my home country for the first time since my family had moved to the US when I was 10. It certainly was a somber time and I may have perhaps imagined this, but I recall most people on the street and on busses and trains making an effort to make eye contact with each other. Lots of silent acknowledgements of our humanity.
