Children not only know how to forgive, they also know that enjoying times with their friends is a top priority. The longer they waste fighting, the less time they have for fun…and they are all about having fun. Seems like a pretty simple equation to me.
Why then do adults have such a hard time forgiving and moving on? It seems that as adults, we want to make sure our partner knows s/he was wrong, that we were right, and then we want our partners to wallow in the mistake. If that mistake at all hurt us, we want our partners to feel that same pain.
