Very nice! As a cancer survivor myself I really appreciate the effort your daughter put into that very special message of hope to anyone who sees it. Your daughter should be commended for the unselfishness and generosity that she chose to bestow upon a person she doesn't even know, yet cares about.
If there were more kids like that here in the US and the world, we'd live in a better place.
I'm just happy to know that your daughter now has a special place in my heart.
You did good Bedo! You raised a fine girl!
