Have you ever considered the fact whether you were an extrovert or introvert?  I have....and I am so pleased that some kind soul finally wrote a book comparing the two styles.     I have always considered myself....shy.....or in other words an introvert.  Oh....don't get me wrong....I can carry on lengthy conversations if required....but I much prefer listening to talking.  By doing so, I can interject comments occasionally if appropriate...or keep quite if I so desire.     Often, if we are attending a social gathering I will size up our companions and decide which one, I believe, will carry the evening so to speak.  Or, I will ask my wonderful soul mate if he is in a "chatty" mood....his comment usually is we are going to see "so and so" so he doesn't need to be.  LOL LOL     I always believed there was something wrong with me because I was not more of a "chatty Kathy"....but now....I realize there probably are a lot more folks out there...
