A New Spin On Diet Vs. Regular

Do you ever feel like you have to give your friends the diet version of yourself?  I'm a naturally intense person - and 99.999999% of the time I'm perfectly content and happy to be that way.  I am constantly in thought, whether I'm reading, driving, eating, sitting outside, sitting inside, putting my shoes on or gassing up the car.  The main issue seems to be the subjects upon which I dwell:  history, culture, politics, theology, philosophy, music, programming, education....  It is impossible for me to see those subjects as unrelated.  I often find myself trying to explain the cause and effect nature of those subjects (and typically along the lines of something happening in the real world) and then I sense the "eyes glazing over" effect with the person listening.  I get so excited about a particular book/subject/article/conversation/whatnot that I find myself "reeling me back in" since there is some default internal response of "C'mon Jim, they don't want to hear the unabridged version".  I completely get the need to be concise; to not overwhelm someone in conversation - and have worked a ton throughout my life to better my skills in that area.  But I gotta admit, the people with whom you can truly let your hair down...the ones that not only don't mind, but actually want to hear the 'unabridged version' of whatever is on your mind....those people are like that first breath you take when you come up from being underwater for almost too long.
