Probably not the ideal question to ask anonymously. It'd make meeting up quite spectacularly difficult. I'd be stuck asking everyone in London "Hi, are you the anonymous guy/girl from the Internet?" and they'd just stare back in confusion. Or they'd turn out to be some grizzled, shifty looking guy/girl who'd say "What? I... yes! Yes, I am! Why don't you come back to my place and see some adorable puppies?" and I'd be a little nervous but it would be rude to say no, so we'd take their car - don't mind the dead pig smell, they'd say, laughing to themselves - out into some quiet corner of an unfamiliar city, calling their friends on an old cellphone to say the word "Orion" before throwing it out of the car window and grinning a tar-stained smirk that lingers on my torso just a little too long for comfort, before finally arriving in some seedy council estate with a dead postman nailed upside down on the gate, and then we'd push past the strangely unlocked door and through the small pile of envelopes and then there'd be these adorable little poodles on the rug and he'd go "So glad you came, mate, most people are put off by my poor social skills" and it all turns out okay.

Which would be a bit time consuming if I have a train to catch.
