There are circles when it comes to friends. The outer circle and the inner circle. The friends in the outer circle are very good acquaintances.They are the ones that you keep in the outer circle because they if given opportunity are capable of changing who you are. They are there because you like who you are and don't want to change. The inner circle are the people who love you for who you are and you don't expect them to change as well. This wisdom is priceless in meeting people.
