2. I go to a class at the School of Life -- How to Stay Calm. The teacher, novelist Naomi Alderman, says that people either come to this class because they have a problem with anxiety (that's me) or with anger (mostly men, she says). I find myself talking to a man who says that social anxiety vanishes once you realise that everyone else is far too worried about themselves to notice you. I tell him how when I first understood that aged 18, it was like a burden being lifted from my shoulders. Then we tell someone else about it.
3. A Japanese man and woman are waiting for the tube. They are flushed, and limp with laughter. It makes me smile to see such open happiness.
