How to maintain friendships "Wenn ich mich um Freundschaften nicht kĂĽmmere, dann geht eine Freundschaft ein, wie eine Pflanze ohne Wasser und insofern muss ich einfach nur nichts tun, dann ist die Freundschaft vorbei." (W. KrĂĽger)
As consistency, vulnerability and positivity strengthen friendships, we could try to maintain our close friendships with help of these four maintenance behaviors:
- Be positive and share joy and happiness.
