People must be wondering about how a little child can know the parents’ feelings. In fact, though they are small, even can’t walk, they are indeed smart. The children will watch their parents’ reaction. If the parents get angry, they know that they can’t do it again. If the parents get nervous, then the children will repeat the action to catch attention.

人們一定想知道一個很小的小孩是如何知道父母的感受的。事實上，盡管他們很小，甚至還不能走路，但是他們實際上是很聰明的。孩子們會關注父母的反應，如果父母生氣，他們知道，不能再做這樣的事情了。如果父母感到緊張，那么孩子們就會重復這樣的動作來吸引他們的注意。
