Kids are great at forgiving and forgetting when it comes to being wronged, and it's a lesson that we can carry into our adult relationships. Perhaps you can't forget when someone has hurt you – but you can forgive, if only for your own peace of mind. Kids don't have the luxury of bailing on a familial relationship when things get tough, so they find some way to be resilient through hardships – whether it's death, divorce or some other problem. In relationships, it's OK to be sensitive to what your partner is going through – but it doesn't have to bring you down. Finally, kids know the value of devoting your undivided attention. It's not simply enough to be in the same room with someone; give your partner your undivided attention once in a while and let go of the other "stuff."
