It's hard to nail down exactly what to say, but it's less tricky to pinpoint the things you shouldn't.  When I lost my grandfather last year (we were very close), I heard stuff like "time heals all wounds," and "He's in a better place," and "It sounds like it was just his time." Blech. No Bueno.  So when writing a condolence card to a grieving person, sincerity and warmth is the name of the game. Beyond a simple (but always appropriate) "I'm so sorry for your loss," here are some examples: -I hope your thoughts of __________ bring you some light during these dark days. -May the fond memories of ________ sustain you and bring you some comfort.  -I wish I could take away your grief, even for just a little while, to help you find some peace during this difficult time. -Know that whatever you're feeling and however you want to express that, I'm here for you.  -If you feel like you need to talk about _______ and what they meant to you, I'm all ears.
