Gah! I have a love/hate relationship with subtext. I can work out subtext very well in movies and literature because I know that it is bound to be there and is a deliberate device used to make things more complex, challenging, and sophisticated. Working out the subtext is enjoyable and easy, and nothing bad will happen if you don't spot some of it. However, when it comes to real life, I am usually terrified and bewildered by subtext. I am always straining to try and figure out what people really mean.
Why can't people SAY WHAT THEY REALLY MEAN?
If I ask an NT guest: "Are you hungry? Would you like me to make you something to eat?" They might say: "No thanks. I'm fine. I'm not really hungry."
If it were me saying that, I would be saying it because it was true. However, when an NT guest comes into my house and politely refuses a meal, they could actually be saying:
1. "No thanks, because I don't like the look of the food you are offering me and wish you would offer me something else instead but am too polite to say so."
2. "No thanks, because I am worried it would be putting you to too much trouble so I will just sit here and squirm while my tummy rumbles instead."
3. "No thanks, because I can't really stay for very long so although I am hungry, by refusing your offer of food I am actually trying to hint to you that I cannot stay for very long, and need to leave soon and go and eat my meal in my own house instead."
etc
etc
etc.
WHY DON'T THEY JUST TELL ME WHAT THEY REALLY MEAN? I'M NOT A MINDREADER!
Basically, when NTs talk, they could mean anything at all. They never actually say what they are really thinking inside their heads (or very rarely, anyway). This is why just being in their company makes me get so terribly ill due to anxiety caused by trying to figure out what the stupid things are actually trying to say. I have to live like a hermit.
