My father and brother had not made my marriage known to their acquaintance ; because , in the very first letter i wrote to apprise them of the union - having already begun to experience extreme disgust of its consequences , and , from the family character and constitution , seeing a hideous future opening to me - i added an urgent charge to keep it secret : and very soon the infamous conduct of the wife my father had selected for me was such as to make him blush to own her as his daughter - in - law
我的父亲和哥哥没有把我婚姻的底细透给他们的旧识，因为在我写给他们的第一封信里，我就向他们通报了我的婚配已经开始感受到它极其讨厌的后果，而且从那一家人的性格和体质中，看到了我可怕的前景一一我附带又敦促他们严守秘密。不久，我父亲替我选中的妻子的丑行，己经到了这个地步，使他也羞于认她为媳了。
