I overheard some domestic abuse today. It was a man talking to his female partner on the phone (I know it was a female partner because he said 'girl' and 'you girls' to her). He was shouting and swearing at her and telling her he was going to turn up at her workplace and 'You're going to talk to me and you're going to apologise or it's over.' He was angry because she hadn't said that she loved him.
(And if you think I was being over-nosy, this was unmissable because he was standing on a station platform yelling his head off into his phone)
I wanted to grab the phone off him and yell into it 'Tell him to fuck right off and you'll get a restraining order if he doesn't.'
Obviously, I did absolutely nothing apart from wishing plague and cock rot on him, because there was nothing I could do. But it was really unpleasant to listen to.
