“Every day is alone in itself, whatever joy I’ve had and whatever sorrow I’ve had” – H.M.
“Right now I’m wondering. Have I done or said anything amiss? You see, at this moment everything
looks clear to me, but what happened just before? That’s what worries me. It’s like waking from a
dream; I just don’t remember.” – H.M.
