Embankment, northbound Northern line platform, a cold winter evening. Two boys, around 19 years old, sit on a bench playing a very popular song through their phone while talking to each other quietly. Ten metres further up the platform, two girls of around the same age sit next to each other in silence.
Me: Boys, as much as I love Carly Rae, playing music out loud on public transport is not allowed. Can you turn it off please?
Boy: It isn't us, it's those girls
Boy: And who the fuck likes Carly Rae anyway?
