I may be a drug addict. I may, too, be a weird human with some social difficulties and rather odd interests and mannerisms
and I may be interested in knowing more about the humans who have an influence on my life, either through direct interaction (friendships and such), or through indirect interaction (like writers writing a story that I read).... but i'm not a killer. And i'm not a true stalker. Again, if I were interested enough, I might try to covertly watch someone, just for a bit, so as to generate a mental profile of the person.... but true stalking is much more than that. And i'd never truly stalk anyone.
And the phenomena of wanting more information of, say, a writer who's story you've read and enjoyed... that's actually not abnormal at all. Most humans are like this. This is why things like paparrazis exist; because there is an inherent human desire to know more about your fellow human brothers and sisters, especially those who have in some way contributed to your life.
I have an intense curiosity of WhatMustIDo's personality and social tendencies, as well as his background. But I'd never do anything illegal, I would most-likely not ever break too many social rules. (I try not to break any social rules; but for some, the process of socialization is a life-long learning experience) And I'd never try to directly invoke fear, anger, annoyance, or any other negative emotion from a person whom I'm curious about. Again, the most I'd do is maybe watch a person covertly for an hour, then be done with it. Or, if I was feeling like a social alpha that day, I might go up and try to start a conversation, but if WhatMustIDo told me to "bug off", then I would apologize, and then proceed to do so.
Curiosity is not a crime. And it is inherent to all of us.
Remember that, anonymous.
