Climax:
When the children go against George (when he hits the mother).
Ending
The problem is solved because George realizes, that what his children want is not the same as he wants and he realizes, that these two cultures can't be united. (you can see this, when George walks away. That is a way to say, that he gives up his intentions). This might be difficult - new conflicts may arise.
The ending is good, because the problem is solved. But: will things remain in this way? Open ending...
