João 4:28

The fact that the woman left her water pot at the well suggests that she felt such excitement at having apparently discovered the Messiah that all but telling others left her mind. The Apostle John may have included this detail because her act had symbolic significance. Some commentators suggested that in her excitement she abandoned the old water pot (ceremonial structure) that was no longer necessary (cf. John 4:23). I doubt this interpretation and tend to view this detail as simply evidence of her excitement. There is plenty of symbolism in this story already that Jesus explained.

It would have been natural for the woman to report her discovery to the men in Sychar since they would have had to determine if Jesus really was the Messiah.
