I was recently talking to Cathy, a friend of mine. She and her girlfriend Sammy were having a tough time in their relationship and had just gotten into a fight. She explained what had happened. They were decorating the house for the holidays together, but Sammy got upset and said it was all for her, her tree, her project. She lashed out at Cathy and left. From Cathy’s perspective, Sammy was having a temper tantrum. She didn’t understand why Sammy was getting so upset. Why couldn’t they have a nice evening together? What went wrong?
