Can you tell me stages of bereaving and bereavement cards?

5 stages.: Dr. Elizabeth Kubler-Ross talked about the 5 stages of grief and not always in chronological order. Sometimes people get stuck in one stage or go back to the previous stage, back and forth: Denial, bargaining, anger, depression and resolution. I am not sure what you want to know about bereavement cards. People send them to express their condolences to the bereave and share your loss.
