This paper focuses on some interaction patterns related to gender in Neighborhood Dispute Cases, submitted to a Local Neighborhood Consumer Protection Office. Community mediation using field research logs and home interviews were the schemes relied on by the Local Office to handle these situations. To deal with the conflict situation, a dispute between a man and a woman is discussed in which mutual behavioral expectations as they related to women vulnerability and consequent loss of the mediating position during the dialogue are analyzed.
