I missed her birthday. But that's how it works with her. From her unfinished autobiography, Smile Please:
"The trouble is I have plenty to say. Not only that, but I am bound to say it. I must write. If I stop writing, my life will have been an abject failure. It is that already to other people. But it could be an abject failure to myself. I will not have earned death.
"Yes, most of it is childish. But I have not written for so long that all I can force myself to do is to write, to write. I must trust that out of that will come the pattern, the clue that can be followed."
