1. There's something rather hopeful about a city so full of bikes that parents and children cycle together at rush hour.
2. At the very back of this slow, near-empty train, someone is singing showtunes, taking requests and enjoying the unusual acoustics.
3. It's been a slow journey, but I pretty much walk on to a Tube train, and then on to a train heading towards home. I've had plenty of time to read, and plenty of time to think about everything I've seen and done today.
