confrontation

Do you ever have those days where you just feel beat down by someone that is supposed to be your friend? How about those days where you just get tired of being talked down to by the same person over and over? How do you confront this person? Or do you NOT confront this person and slowly pull away from their friendship? What would you do? How do you approach the subject without full on confrontation if the person asks why you are “avoiding” them?
