> think you're talking to them

Yeah that's still weird. Last time it happened to me was in the City of London near Liverpool St (ironic as we're talking about banking phonecalls). Out of nowhere a guy walking towards me starts speaking, for all the world like he's trying to talk to me, so I stopped and said "Hey, can I help you?"

Nope, strides on past, then I noticed the airpods.

Thanks to binge-watching CGP Grey's channel this week, I know exactly what you're referring to, and why you wrote it fully-specified like that!
