My grandma was the best cooker in th world but could make the most delicious dishes. Once, I just couldn’t wait for the Spring Festival dinner. As I was about take a piece from a cooked duck, I saw Grandma in the kitchen looking at me. Shake his head, she said, “It’s not a good time to do that, dear.” I apologize and controlled me at the best till the dinner started. You know, that was a dinner we had waited for several month.
