I can't read your mind. There are many minds I would not want to read. It would be interesting to read a visitor's mind while they read my post.
Given enough details of a situation and a few visual cues, many people are able to conclude at least a general idea of a person's thoughts. This is very useful if that person intends to kill you.
I've been known to seek more details. Details can support your ideas, provide insight, prompt new ideas or clutter your mind. Have you heard of "analysis paralysis"? You don't need every last detail before taking some action. You also will shorten your lifespan constantly running wild in the dark.
So what's brewing in your mind now?
