There will be no more weather for a while. 
I'm on the bus, on my way to the tube and then to the airport, where I'll fly tonight to Hong Kong. 
Once I get on the tube, there'll be no more outside weather, just a series of fabricated environments. 
One of the last things I see before this encapsulation begins is an old lady sitting at the bus stop in the rain. I am looking out of the bus window, on the lower deck, looking right at her, and I smile. She seems surprised, but she smiles back and gently raises her hand into a tentative wave. I beam and wave back. She beams. Just for a moment, as the bus pulls away, I think - I love human beings. 
Sometimes, I love human beings. 
And I know she's feeling the same thing.
