I felt a little 2. (confusing) at first—Why did we need two pairs? My brother looked almost 3. same to me.
My mum smiled and explained that using serving chopsticks is a 4. (improper) table manner in Chinese culture. It shows respect for others and helps prevent the spread of germs. "5. using serving chopsticks to share food, it's impolite to touch dishes with your own chopsticks," she said gently. I tried to pick up some vegetables with the serving chopsticks, but my 6. (elbow) kept knocking against the table. Mum reminded me to sit up straight and keep them 7. the table. I felt so embarrassed when I dropped a piece of tofu on the plate, but everyone laughed and encouraged me to try again.
After the meal, I was getting used to 8. (use) serving chopsticks. It made me realize that small cultural habits can make a big 9. (different). Now, whenever I eat with friends or family, I always remember to use serving chopsticks, so everyone can enjoy the meal 10. (happy) and healthily.
