She started by saying how it was fun. I acknowledged and validated. Then she said that her biggest memory was of how hurt she when we got home as I neglected/ignored her for about 45 minutes while I was working on our home stereo. I couldn't argue with her as she had really challenged why it couldn't have waited till morning. That's how she goes about positive/negative bashing...
So you acknowledged and validated when she said it was fun, but not when she said it hurt.
