Misty lane

It's been a very foggy day in Oxford today. The fog usually disappears by the afternoon, but when I walked out of my lab at 6:20 pm, it felt like being in the cloud. The visibility was probably just a couple of metres. It gets dark quite early in the UK now, around 5 pm. St John's Street felt like a crime scene in the Sherlock Holme's detective books. The light was dimmed slightly and refracted by the heavy fog, and all of a sudden Jack the ripper would jump out...

Best of luck to Tom for his exams! Ga yu++ (加油)!
