This whole Gospel story was about Jesus speaking to the woman [something that men didn't do in public].

Relationship MUST occur First----otherwise---nobody is going to achieve any kind of "conversion' or confess any sins.  And the Gospel story didn't say that the woman confessed her sins.  Jesus ALREADY knew what her life was like.  The very fact that she was getting water at mid-day---states that she was considered a public sinner [the Samaritans had their sense of morality, too].

BUT Jesus' individual approach with the woman was great.  And he spent two days in that town speaking to many people.
