This is Why I've Never Had a Girlfriend!
Yes, looking back I think that's occasionally happened to me, too, but only very rarely.
There was one time in particular that I was waiting at a train station and this girl came up to me and asked me when the next train is. I just said "15 minutes" (or whatever), but she then asked something else like where it's going and at this stage I was thinking "huh? why the hell is she asking me this stuff? do I look like I work here?" So I mumbled something again, all confused. Nothing too unusual about the questions themselves, but the thing is, she was standing really close to me the whole time (far closer than was necessary) and it just seemed to take a lot of time and effort to ask such simple questions. It's hard to put my finger on it, but there was definitely something unusual about those trivial questions. In fact, when she was walked up to me she had this look like she was on a mission - I actually thought she was about to try to sell me something, so I was surprised even by her first, perfectly ordinary, question. It was only later that it occurred to me maybe she was interested in me. I was wearing a suit and tie that day, which I don't normally do any more, so maybe that helped. She was very cute, too! I was kicking myself later for not at least giving it a go - even though, in all likelihood nothing would have come out of it anyway.
That's a really good way of putting it. I never really though of it this way, but it makes sense. Thanks for the explanation!
I probably would have thought that, too. There are multiple possible explanations for anything a person says and, at least in my case, assuming that sexual interest is the most likely explanation seems rather foolish. But I think what an NT would do in this case is simply jump on the explanation that most appealed to him (she's interested in me), ignore all others if they even occurred to him in the first place, and just go ahead and ask her out. He may well be right, too! But even if he turned out to be wrong and she rejected him he would just think "what the hell is wrong with her? women!" rather than analysing what he might have done wrong. Maybe we just think too much for our own good!
