Ed, your moving tribute to your mom reminds us that achievers in life are not only those who build companies or who "change the world" in some public sense - but also all the good, decent, and loving people who spend their lives quietly helping and inspiring others - your mom quite evidently among them. I went through this too in the past couple of years and there are few things in life more painful, even when we expect it. Your mom must have been a very special person. I am sorry for your loss.
