contrary to what many believed, my father was kind and tenderhearted, especially towards his family. His forbidding sternness seemed to melt into love, kindness, and easy familiarity when he was with us. Especially with me, his acknowledged successor to the throne, he would play lightheartedly. When we were alone together, he would sing me little songs; I don't remember his ever doing this in front of others, but when only the two of us were there, he would often sing to me.
