Children grow too fast. And we have too much to do in too little time. I see things on the Internet and I am deeply moved. Often, I am moved to sadness. For instance, this video (h/t Victor Agreda Jr) is a fantastic means to explain an open API to someone. As I watch it, I feel a giddiness over the explanation and the hopes of using it to explain APIs to my children, and I feel a heaviness in my chest, for I have never played War, or many card games, with my children.
