Yeah the most unbelievable part of this is people randomly chatting in London.

I live in London, and I remember flying to Ireland at some point, and I was seated next to an Irish lady returning home from holiday who sparked up a conversation.

My initial reaction was "Why the fuck are you talking to me?" because I had lived in London so long I was thrown off by a random person sparking conversation. But turns out she was just a lovely Irish lady flying from from holiday
