Inside other people. Part 1

This is so obvious and many might think that I’m an idiot for not really thinking about this until maybe a couple of years ago. Let me explain what I mean by this. Of course, throughout my life, I’ve many times pondered what someone else might be thinking of, whether it concerned me, something- or someone else. I’ve even engaged in vain fantasies about being admired by others. I still do sometimes, even though I try to stop myself when my thoughts wander in that direction. 

What am I talking about then? I’m talking about consciously thinking of the fact that we only have access to what’s inside our own heads. We don’t even have direct access to reality. Only our senses’ interpretation of it and our thoughts and feelings about it.
