I like when I turn and look at the door before someone knocks.
Reminds me of something my wife used to say. We'd be approaching a bus stop along a road about 60 metres long that was exactly perpendicular to the bus stop. She'd take maybe a minute to cover the ground, longer if there was traffic going on the road between us and the bus stop. And buses came at intervals of five minutes or less, because London. So for her the frequency of buses in London actually contributed to her anxiety. She used to say that she felt that she was always too late for the bus.
Now we have moved out of London, but we are in a very nice metropolitan area of the English northeast. We live very close to a bus stop but you can't see the stop until you're very close to it. The buses only come every ten minutes, but she's fine with that. She's waiting longer for every bus, on average, but unless a bus happens to sail past us on our very short journey up the street to the bus stop (which is very rare) she doesn't feel bad.
They say a watched kettle never boils. I think there's an element of cognition that is quite closely bound to experience. So if you often find yourself walking down the street and notice a bus stopped there, you'll tend to get the idea that the universe is malevolent and that it loves to dangle your prize just out of reach. But if you know a bus will come anyway and you don't ever see a bus you can't board, you don't get anxious and don't feel so paranoid.
I hope that makes sense. I think it's tangentially related to your idea of watched doors. Perhaps you look at doors a lot but you don't find significance unless somebody comes to the door.
