A sweet woman sits under a tree and works as a mediator. If you're having a fight with someone, bring them to the sweet woman under the tree and she'll mediate for the two of you. Problem solved! Thanks sweet lady!
You go to pay the woman for being your mediator for you two but she just says, "Bye ばい)." You try to hand her some money and she stares into your eyes. "Bye." Oh... okay, bye then.
