What do you say to someone who has suffered a personal tragedy like the death of a loved one?

I think people use cliches. I don't like them. I have found that being sincere is best. I say that I am here if you need to talk. I am here if you need anything. And I only say this if it is true. I think people should follow-up a bit after the funeral. In the weeks that follow, people disappear and the loved ones that are left are forgotten. That is when they are alone and really need company. And food can help show love too. I also like to share a memory of that loved one or how they effected my life. That is special especially on a card. A hug makes a difference because it is caring. People find it difficult to be comforting when someone dies, but people know you care.
