If I do the school run by tube, it takes 20 minutes longer than if I do it by car.
The car has a powerful heater, blasting warm air in my face and on my feet. The tube has drafts from the doors which all open at every station.
On the tube, I listen to my music quietly on my headphones and I don't sing out loud at the top of my voice as I do in the car.
But if I go by tube I can admire some magnificent sunsets at this time of year. And O and I get to chat as we walk home from the station; if we are lucky we find some treasure too.
