some of the best advice that i have heard regarding 'men', came from a little old black man that was a patient of mine. he was in his "52nd year of romance with the most beautiful woman". i tend to talk with the old folks about my romantic woes, they have the best insight. 
the gentleman explained to me that men have an innate quality to "construct"; men are brought up to build things- roads, bridges, buildings... 
and his message concluded with, "if he wants to be with you, he will build his way to you. men are resourceful. you don't need to ever track a man down. in fact, do him the favor of not doing so. let him be a man. let him be a constructor. then, he will forever be proud of his greatest accomplishment- you."
too bad i'm not one to follow good advice.
