The journey back home in Istanbul when you realise you forgot to take a photograph of the Aegean or anything else remotely photogenic earlier in the day, which was spent poolside, swimming and chatting until the last possible minute. The visual potential of an interesting pattern of lights on the bus failed to be realised in the image, but it's the only pic I took today.

Didn't learn about the terrorist attack in London last night until lunchtime today. No words.
