A balance is also needed in interpersonal relationship/人間関係/人際關係/인간 관계, just now above was about “intrapersonal” relationship. Interpersonal relationship is in the form of limerence, love, solidarity, regular business interactions, or some other type of social commitment. Relationship must be in equilibrium, whereby the two parties must give something to each other in order to strengthen the bond. It is sometimes very hard when more than one factor (emotion (heart), mind) come in contact with relationship. In any case, be calm and don’t take rush actions, cause the friction it may cause might weaken the relationship.
