Elizabeth Edwards
With the passing of Elizabeth Edwards, whom I unfortunately have learned more about in her death than in her life, I have seen quotes from her all over the interwebs.
This one in particular, I really liked, and so I will pass it on.
(To the unaware, she lost her teenage son in a car accident.)
"If you know someone who has lost a child, and you're afraid to mention them because you think you might make them sad by reminding them that they died--you're not reminding them. They didn't forget they died. What you're reminding them of is that you remembered that they lived, and that is a great gift."
