I can tell you why I personally find it hard to express emotions. For me, it's an underlying trust issue, mixed with the fact we're all on different levels of consciousness; which definitely makes it hard to connect with people. That's why intelligent people tend to go loopy after a while. They lose contact with reality, and I'm borderline close to this! As I've been a deep thinker my whole life, I didn't need to have my mind opened by drugs, people and whatever else seems to be educating people these days. Also interesting post. (:
