《史记·七十列传·苏秦列传》
过了三天，她丈夫果然到了，妻子让侍妾端着有毒的酒给他喝，侍妾想告诉他酒中有毒，又恐怕他把主母赶走；可是不告诉他吧，又恐怕她的毒酒害死了主父，于是她假装跌倒，把酒泼在地上。
居三日，其夫果至，妻使妾举药酒进之。妾欲言酒之有药，则恐其逐主母也，欲勿言乎，则恐其杀主父也。於是乎详僵而弃酒。
Three days later, her husband sure enough arrived at home and the wife had a handmaid serve him the poisonous wine. The handmaid wanted to tell him that there was poison in the wine, but was afraid that he would drive away his wife. However, if she didn't tell him and the poisoned wine killed her master, it would be all her fault. In the end, she pretended to fall and spilled the wine on the ground.
