Dear Richard:
We are shocked by the painful news of the passing away of your grandmother.She was a fine old lady,well-loved and admired by all who knew her.I quite understand how you feel now,but you are in duty bound to look to your own health and take care of your family.
My family and I send our heartfelt sympathy.
Yours sincerely
Mary
