Kana/Atma wants to tell a little example on this topic with the intension to give some "insights" for daily life, for the growing and unity of the Buddhaparisāta and not to disgrace someone.
Yesterday, when Kana was in the Monks Kuti, some of the laity came into the dwelling place of the Monks and took a bottle of water. When he realised, that kana was in the Kuti, he tell kana :" I take this, ok?!" and kana answered :" Atma do not know who is the owner of this, this bottled water was not given to Atma, so he is not the owner and because of that, Atma is not able to give it to a another person." the person responded :" Yes, Yes!" and continued with open the bottle and drank the water.
