Late night call

I was in London this evening for a social event and, returning home via Kings Cross station, I just missed a train.  That's when I discovered that the new, "improved" timetables had halved the frequency of late night trains, so I had an hour to waste before the next train.

Never mind, I had my camera with me so it was a chance to wander around for some late night street photography.  I captured this shot just outside the station.  There were still plenty of people around, but this guy was sitting by himself against a wall, engaged in a lengthy conversation on his phone.  I quite like the sense of isolation.
