If you don't know what to say, it's OK to be honest and tell the grieving person that you're at a loss for words, notes HelpGuide.org. For example, you might say, "I am not sure what to say, and can't imagine how you are feeling." The person experiencing his mother's death needs to know that you care and will be there for him through this difficult time. Tell him that if he needs to talk about his mom -- or anything else -- you're there to listen.

Share a favorite story or funny anecdote about the lost loved one. Say to the grieving person something like, "I remember how your mother used to make us hot chocolate on snowy days." Though your words may trigger tears, they will also bring back fond memories. The person experiencing the loss is likely afraid to lose those thoughts of her mother -- and will appreciate your willingness to talk openly.

Think about how you can help your friend -- and offer your help, notes HelpGuide.org. Say something like, "I can watch your children on Saturday if you would like some time to yourself." Your friend needs specific offers of help while she is grieving. She may not have the mental strength to think of what she needs at this time.
