It may take a couple of weeks, but at some point you'll be walking through Queens Arcade and realise that it's the shopping centre from 'Rose.' At which point, you won't be able to stop checking if the mannequins are actually Autons. The same goes for suspecting the statues around the town centre of being Weeping Angels, and avoiding the paintings in the National Gallery in case they're Zygons. On a related note, you'll spend the better part of three years looking out for the show's cast, and getting inappropriately excited whenever you spot a BBC van.
