A couple of days ago Austin and Mari were batting their arms at each other and stealing each other's toys. This happens regularly. They stopped (this also happens regularly). Then Austin stood up and bumped his head on the kitchen counter and started crying.
Julie sat down with him and was making sympathetic noises and patting him when Mari crawled over. I think all three of us (Julie, Austin and me) expected Mari to attack him while he was down, but instead she crawled into Julie's lap with him and then reached up and kissed him.
