There were mostly grey and wet days with classic winter vibes in London. It was rainy almost every day, cold, and a bit windy at times. Only one day felt sunny and bright, which was a nice break from all the rain.
Side note: As I am writing this in a cafe in London near the underground station called Angel, I'm looking at the sun shining down on me, and I feel uncharacteristically happy to see the sun. It's truly a blessing in London that I take for granted in the U.S.! I want to capture the rays of the sun so they never go away.
I saw pigeons. (So many!) An occasional squirrel appeared here and there. Dogs were taken on walks and were seen with their owners on the tube. I even saw one in the basket of a Lime bike! Just now, I realized that I have seen zero cats, unfortunately!
