Slowly, Professor Thompson got up and walked to the windowsill. He gently pushed the window open and looked out. "I have never made a big mistake in my life, and I did it with no malice, but I did kill a person. Since the fire, I couldn't sleep every night. Now I've said everything, I feel relieved."
As he spoke, he suddenly seized the edge of the window with one hand, stepped on the sill, and climbed up.
Sophia startled. "What are you doing?"
Professor Thompson gave a miserable smile, "I don't want to go to jail in such an old age. I also don't want to get anyone into trouble. I'll take all the responsibility."
Sophia didn't want him to die. She hurried up and said, "Get down. Yes, you made an irreversible mistake, but you don't need to die for it. Think about your family, how sad they will be!"
Professor Thompson shook his head, "They'll be ashamed of me. People like me…"
