Condolence and sympathy cards can be purchased at stores such as Hallmark and American Greetings. Condolence cards are typically given to someone to express sympathy when a loved one has passed away. They let the recipients know that the card giver is thinking about them and cares.
Emily Post recommends that condolence card writers focus on how they truly feel, rather than the manner of death. Other examples are to include a specific memory of the deceased or an offer to help. If the writer was close to the deceased but not the family, the card should be addressed to the closest relative. If the writer did not know the deceased, the card should be addressed to the relative the writer knows best.
