While eating in a restaurant, I reprimanded my four-year-old son for speaking with his mouth full . "Mump umn Kmpfhm," was all I heard.　　
"Drew," I scolded, "no one can understand a word you're saying. 　　
"He says he wants some ketchup," my husband said calmly .　　
A woman sitting nearby leaned over and asked, "How in the world did you understand him?" 　　
"I'm a dentist," my husband explained.

在饭店吃饭的时候，我申斥我4岁的儿子，因为他满嘴食物在说话。“喔、呢”，我听到的就是这些。 “祖，”我责备道，“没人明白你在说什么。” 　　
“他说他要一些番茄酱，”我丈夫平静地说。坐在旁边的一位妇女靠过来问道：“你究竟如何明白他的话的呢？” “我是牙医。”我丈夫解释道。
