Hot in the city

For my meeting in Cavendish Square this afternoon I chose to take the Tube to Regents Park and walk, limiting my air pollution exposure. It's not often I can say that the Bakerloo Line is a cleaner alternative.

However, everything went seamlessly, including a punctual number 6 bus on the way back.

I was wearing sandals and a skirt so had to slow down from the fast pace I normally maintain in trainers and jeans. Maybe that's the answer.
