Explanation:
sympathy letter for an accident is written to express your grief and condolences for one who has met with an accident. This kind of letter is written by relatives or friends whenever an accident has taken place. The sympathy Letter must be written as soon as the writer comes across news of the accident. Your letter of condolence should have an affectionate, sensitive tone. If you knew the deceased, you could write about a beautiful thought of that individual. If not, you can state how much the individual meant to the receiver of the letter.
