When we're kids we play around; we're police and robbers, pirates, we build tree houses and pretend we're in the jungle. Every fantasy becomes reality... we're someone else for a couple hours - and it feels real.
Then we grow up, and the fun and games are moved to the bedroom. Role playing feels natural to some, but most people can't seem to relax. Reality is so real, fantasy never can be. We pretend with feelings, little lies, not with fun and games. We feel stupid. And awkward.
