Humor joke: I'm hungry and no one cooks for me. Can I not worry?

Humor joke: Once upon a time, two scholars traveled together. Jia Xiucai said, "People say,' When a child travels a thousand miles, his mother worries, but when he travels a thousand miles, his mother doesn't worry. "I don't think this is right." A scholar asked him why he was wrong. Jia Xiucai said, "To tell you the truth, my mother has just visited for a long time, and I am very worried at home." B scholar listened and said, "I can't see that you are still a dutiful son." Jia Xiucai said, "I'm hungry. Nobody cooks for me. Can I not worry? "
