A sympathy card is a type of greeting card sent to express condolences to someone who is grieving the loss of a loved one. These cards often feature comforting messages and can include personal notes to show support and care. They are typically sent during difficult times, such as after a funeral or when someone is facing a significant loss. Sympathy cards can be purchased at stores or made by hand, allowing for a personal touch. Common themes include nature, peaceful imagery, and heartfelt quotes. Sending a sympathy card is a thoughtful way to acknowledge someone's pain and offer comfort during their time of sorrow.
