My dear Richard, my deepest condolences for your mother. I have lost mine 23 years ago, on May 27th, 1998 (I' ll be 46 in August 13th) and I still miss her, my dad too, who died 6 years ago. I made a donation in her memory, your mother, here in Cyprus, where I live. I am listening to "On the Nature of Daylight" of Max Richter and I' m sending you my thoughts. May her soul rest in peace.
