Quantum weather butterfly
The interaction is more understated but it does happen. On my way to my first ever Maiden show I was wandering around that concourse near the London Eye and I very quickly noticed that, although none of them actually spoke to me, anyone else wearing a Maiden shirt would smile and acknowledge me. But as regards actual conversations, I think no-one wants to be the one to initiate it (which, admittedly, is a very British thing ...) But that, too, does happen - I've witnessed it. I think it needs to happen more often.Must have been foreign people doing that. British people would never do anything of the sort, particularly in London.
