How did The doctor not realize?
*****SPOILER ALERT*** please do not read if you haven't watched the movie.
Ok according to this, because the doctor was dead, no one except the boy (because he could speak to dead people) could communicate with him right?
Does that mean that the doctor didn't communicate even one single word to anyone else all those months? I mean even if his marriage deteriorate, there would be times where it would be unavoidable to talk for some stuff when you're living under the same roof. People don't go MONTHS without speaking even some mundane thing. And what about the other people? Like maybe if he went to buy something from a shop? Didn't he realise that the shopkeeper neither saw nor heard him?Or let's say he tried to take a cab? I mean, people HAVE to do day-today stuff like that all the time. For all those months when he seemed completely invisible to every single person, wouldn't he have started wondering what was up?
