M entertained our car and the two cars next to us as he did physics experiments on the Underground. He kept us all entertained for about half an hour!

The kids and I took the train and underground to meet Dave for lunch today. We found a pretty park with lots of seating. Unfortunately, one can only enter with a privilaged key; therefore, we sat on the outskirts facing oncoming traffic. Even the benches outside the park were not allowed to look at the park. We had fun watching all the traffic.
It was really cold today, so M gave his jacket to K. What a loving brother!
