At around 6 o’clock on a weekday evening, London goes crazy. I have only lived here for a month or so but I realised quite quickly that it’s best to avoid 6pm. The streets are not safe, they are filled with a stampede of people who will walk right through you to make sure they get home in time for their dinner. It’s even worse underground, that is, if you can even make it underground. The entrances to tube stations grind to a halt as men in suits clog the ticket barriers and the streets outside.
