Lightning had lost its partner, so it was naturally depressed.
Mr. Oster's heart ached terribly. He patted Lightning. "My wife Jane passed away and Snow White also went with her mistress. But I'm your master, and Jane would want me to continue my life. You have to stand by me."
Lightning whinnied and rubbed its head affectionately against him. Finally, it was willing to eat some carrots.
"Take Lightning over to have more food," Oster instructed as he watched the staff bring Lightning away.
Greg saw the sadness in Mr. Oster's face and was afraid that he would return to the state he had been in for the past three months.
After Mrs. Oster passed away, Mr. Oster almost broke down. It was only after watching the video that she had specially recorded for him a few days ago and hearing her say that she hoped that he would continue living a good life, that he finally pulled himself together.
