I was on a train in North Yorkshire once with a guy from Devon who was arguing about who was better...the beatles or the rolling stones...and i honestly didn't realise that he was being serious until he properly took the hump at me for laughing...as we came out of a tunnel, as i recall. I explained that I genuinely had never encountered anyone who actually thought that there could have been more than one answer to that question. Especially not one that rhymed with "bowling phones"
Oddly enough...coming out of the tunnel literally made me realise I perhaps had tunnel vision.
Good luck to them anyway. I think it's quite good that they can still be arsed with it all. They're still waiting for their first tuppence of my pocket money...not that they need it.
