How did Georg respond? Why do you think he had a similar change of heart?

From the text:

“How the whole region would stare and gabble if we rode into the market square together. No one living can remember seeing a Znaeym and a von Gradwitz talking to one another in friendship. And what peace there would be among the forester folk if we ended our feud tonight. And if we choose to make peace among our people, there is none other to interfere, no interlopers from outside. . . . You would come and keep the Sylvester night8 beneath my roof, and I would come and feast on some high day at your castle. . . . I would never fire a shot on your land, save when you invited me as a guest; and you should come and shoot with me down in the marshes where the wildfowl are. In all the countryside there are none that could hinder if we willed to make peace. I never thought to have wanted to do other than hate you all my life, but I think I have changed my mind about things too, this last half-hour. And you offered me your wine flask. . . . Ulrich von Gradwitz, I will be your friend.”

Once again, the fear of death opens the hearts of even the hardest of men. Ulirch and Georg have both come to the realization that in light of what's important.... life...... their feud is meaningless.
