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

Maybe it depends on where you are and the cultural makeup of the part of London you're in, then?

As an aside, I used to work for the company in Glasgow that build The Daily Mash's website before they got all into the ad-heavy money-at-all-costs thing. It used to be much better and the guys behind are actually pretty decent.
