There is an old saying that goes something like, "Show me who your friends are and I will tell you who you are." It mainly has come to be an admonition with parents raising teenagers to watch carefully the friends the kids bring home from the neighbohood or school to keep them with a good crowd and out of trouble.

Have You Done Friend Forensics On Others And On Yourself?
We all add friends based on perhaps our work environment and also some common levels of interests in things. As adults in modern times with tools like blogging, Twitter, Facebook, Google Plus, Linked In, we add more CONNECTIONS and it is looking at THOSE connections and also the real world offline face to face people you have around you, psychologically it speaks VOLUMES of who you are. Probably getting down to the core maybe TEN people that are "friends" to you tell you inside you who you really are. You will share so many personality traits and ESPECIALLY VALUES in common. In romantic pursuits I think there are many "outlier people" we "TRY" to see if the opposites attract has any validity to it, but that is a trial and error phase we go through. COMMONALITIES is what they say endures.
Not to put a right or wrong or a judgement on what you find learning about others or yourself with CHOICE OF FRIENDS but BETTER UNDERSTANDING is the goal.
