I feel very rude. On the last high-speed train to Nanjing, a lady in her fifties bought a hot rice set meal and braised chicken legs, which was a refreshing meal. The big brother who eats instant noodles next to him can hardly swallow it. Finally, I ate a cup of fragrant milk tea and fell asleep leisurely. Few people eat on the high-speed rail. A better set meal costs 50 to 60 yuan, which is not delicious. You said that you ate so well and slept so soundly on the high-speed train, which must make people jealous and hate. All the above are jokes. I don't mind at all, and I don't think it's rude. Just be careful not to spill the soup on others. Why do you call them little sisters? All the good-looking people are little sisters. You really haven't seen a beautiful, well-dressed 50-year-old woman. Besides, I'm in my thirties, and I don't feel disobedient when I call my little sister.
