I Never Regretted Leaving You
Robert suddenly burst into laughter and said, "Haha. William, oh William, you have your days too. Weren't you quite skilled at chess before? How come today you can furrow your brow and kill a fly?"
"Your chess skills have declined. Could it be that you've been idle all these years and your brain has become dull?"
William heard Robert's voice, looked up, and exclaimed excitedly, "Oh, Robert, you're here?"
After greeting, he immediately retorted to Robert, "Don't just focus on making fun of me. Let me tell you, it's not that my chess skills have declined or that I've become stupid, it's just that the opponent is too strong."
