This vagrant was watching buskers in the piaza, Covent Garden. I took a few of him (he was really not quite 'with us' so he was completely unaware. He was drinking from a plastic cup something that looked like orange juice (obviously heavily spiked) and tried to cover up the fact he was drinking. This last vestige of dignity and pride was upsettting as it was obviously all this guy had left, this shot seemed to sum everything up, almost looking over his shoulder as he takes a sip.
Covent garden is usually associated to tourists in London. But there is even real life, there. Great capture, if he really didn't want to be photographed, this is a try to enter in his world and comprehend it.
