Life was a fairy-tale, then, it is a tragedy now. When I was 43 and John Hay 41 he said life was a tragedy after 40, and I disputed it. Three years ago he asked me to testify again: I counted my graves, and there was nothing for me to say. I am old; I recognize it but I don't realize it. I wonder if a person ever really ceases to feel young - I mean, for a whole day at a time.
