Hi John,  Interersting subject here!   I was reading on this actually not too long ago, somewhere I took a personality test which concluded me as an Introvert.  alot of people would not believe that of me, because I do love people and can talk it up in a crowd and meet a million people at the sore etc.  A distinction was made regarding "shyness' indicating an introvert, and some in the forum here have also mentioned that.  There was one thing I read that still clicks with me.............

Extroverts are energized by interraction with alot of people and Introverts are more drained by alot of people, but they are energized by being with themselves.  Or...they look interiorally for their source while Extroverts look exteriorally. 

I see people who can spend hours with people around and still function in life!  ha ha!  Some of these people do appear as the sweet, quiet ones who "are not" the big life of the party also!  At the same time they are found with people/friends around them; they seek out people do be with and do things with etc.  They love having the whole family visit and can actually survive it for days, and with pleasure!  It's life to them.

Introverts need to Retreat and get a Big Break to recoop after Christmas or any big event; they need to recoop over a whole lot of things that took time away from their personal serenity.  They get their charge in life from their own interior!  They may love people but they need time alone to re-generate, and Yes, as some have said...I also...Love Most....One on One!

Naturally we all have shades of both, so that some are more so this way or that.  I realte to you John and others who've been accused of not caring because you didn't participate.  I can do it and Love it...and have a grand time....but boy will I then be happy to be "all" alone for awhile!  And I do really relate to this....that I get my life source it seems from my own solitary time with just me and my many thoughts!
