There's a conflict of interest. I've just realized this, but I think I see what it is that makes some stories or people interesting to hear and some not.
It's a conflict of interest. When you are the one telling the story, a story you're excited about and want to convey it in the most interesting way possible. You don't want to give away any spoilers that will ruin it. So you take your time and explain everything in detail. Because that's how you would've liked to hear it, or so you imagine. The only reason you wanna hear it that way is because you already know everything, and now you're just going over it the second time.
Other people, on the other hand, have absolutely no idea what your story will be about. They want to know right away. You could tell them in one sentence, but you wouldn't feel satisfied with that. You want to paint the story in its full colours and detail. But other people want to know it as soon as possible. They would love to hear all the details if they already knew the big picture.
I guess the problem is that communication using words takes time; it's not instantaneous. If it were, we'd have no problems.
Personally, I don't even like the idea of movie or book titles, because they give away some of the surprise for me. Yet I want to know in advance if the movie or book will be interesting to experience. It's a conflict of interest.
I'm sure I could've worded this exact idea in just a few sentences, but I haven't. Why? I don't know, it's hard, and it's something I'll have to think about more and hopefully work on.
