“You better learn to answer a man when he speaks to you!”
It’s a rainy afternoon in east London and two women are writing these words on a pavement in coloured chalk.
The words are a catcall – shouted by a stranger to a woman walking down a street in London.
The trend of writing out catcalls started in New York and now it’s spreading to other cities around the world.
The woman who started the idea says she wants to stop “street harassment”.
