If you treat people right, they will treat you right ninety percent of the time.  -- Franklin D. Roosevelt

I've always believed in common curtesy and positive interactions.  I try to be nice to everyone I see, even when I'm in a bad mood.  I try to limit my frustration to when I'm alone.  I try to be aware of others around me.  I try to make room, say please and thank you, stay in my space, etc.  I am not the center of the world.  I shouldn't act like I am.  And for the most part, my treatment of others has been rewarded with reciprocal good thoughts and actions.
