I'm not the most observant person in the world. I think it might have something to do with my short attention span and my general slowness. There are cues that I tend to miss out on that lead to both hilarious and often times awkward outcomes. Never been good with 'hints'. It's why I always ask my friends to be very clear when they speak to me. Hints almost always go over my head.
I'm always impressed by observant people. Those who pick up certain body languages and expression and the ones that like to interpret certain behavior. I've always wondered what that would be like.
Some of my favorite shows are Mentalist and Endgame as well as the original CSI. I love the way the characters are super observant of minute details that escape the common person. I've always wondered how their minds worked, what made them the way they are.
