When my boy was two years and four months old I went to America, and was absent three months. He was perfectly happy in my absence, but was wild with joy when I returned. I found him waiting impatiently by the garden gate ; he seized my hand, and began showing me everything that specially interested him. I wanted to hear, and he wanted to tell; I had no wish to tell, and he had none to hear. The two impulses were different, but harmonious.
