《宋史·列传·卷五十七》
朋友为了不影响他的考试，将报丧信藏起来没有告诉他。司马池心里十分不安，晚上也睡不着。说 ：我的母亲素来多病，家里怎么会没有异常之事呢？ 走到宫城门边，徘徊着不想进去。
池心动，夜不能寐，曰： 吾母素多疾，家岂无有异乎？ 行至宫城门，徘徊不能入。
His friends, in order not to affect his examination, hid the news from him. Sima Chi was very worried, and he could not sleep at night. He said: "My mother has always been sickly, how could there not have been disturbances at home?" He went to the palace gates, hesitated, and was reluctant to go in.
