Hi Fisherman,
The mere fact that she was alone in the heat of the day suggests that she was not appreciated or accepted by the other women in her community.
I'm sure if the Samaritan woman was appreciated, she would have been with the others in the cool of the morning to fetch water from the well.
Perhaps, like Jehovah's Witnesses, these women felt ostracism was a loving provision to motivate sinners to repent.
