JI.Jambu 129 Bandung 30 th January 2017 Dear Fred, It was a real sorrow that I heard this morning of your great loss. I knew your mother was ill. For your brother told me several weeks ago. However, as he at that time did not seem to think. The illness was very serious, the news of your mother`s death came to me as a shock. You have my sincere and heartfelt sympathy, my dear fellow, in your sorrow. I know you will feel it deeply, for you always thought so much of your mother and loved her so truly. I feel it also as a personal loss to myself for your mother was always very kind to me. I admired her a good and noble woman. Her death must be a terrible grief to your father too. Please assure him of my sincere sympathy. Words, I know, are poor comforters. "'The heart knows its own sorrow", and in such sorrows we are always alone. However, it is not mere words when I say that I feel with you in your sorrow. Your sincere friend, Jack "You have my sincere and heartfelt sympathy, my dear fellow, in your sorrow." What is the closets meaning of the underlined word?
