笔者曾问赵翼如：为何写《单身母亲手记》？她爽直地说：“天底下最不能伤害的是孩子。”在小学作文课上，老师布置她儿子写一封给爸爸的信，他苦恼极了。在他出生之前父母便离异了，父亲看儿子仅有几次，对于从小就缺少父爱的儿子来说，有的只是恨，如何能够写得出这封信呢？ I once asked Zhao Yi Ru: Why write “single mother’s handwriting”? She said straightforwardly, “The worst thing that can not be done under the sun is a child.” In the primary school essay class, the teacher distracted the teacher by arranging her son’s letter to his father. Before he was born, his parents divorced. His father saw his son only a few times. For a son who had no fatherhood from an early age, only hate. How can he write this letter?
