To be here is to be alone surrounded by people – at once watched and invisible. Over these two hours we keep inquiring what democracy looks like, who owns these streets, and whether, if the people are united will they ever be defeated? The answers to me are clearly: not this, not us, we’re not, and, inevitably, we will be. The demonstration ends after about the length of a movie, and everyone goes home feeling better – as if we’ve done something, as if something’s been done.

I go home sick. Throw up my Burger King into the toilet. Check Twitter to see the protest trending for a moment, then gone.
