Suddenly, Cranes! Thousands of them!

1000 paper cranes.  Based on an ancient Japanese legend, any person who can fold 1000 of them will be granted a wish by a crane.  There's also a more contemporary story of Sadako Sasaki, a young girl who tried to fold 1000 cranes to fight her leukemia as a result of the bombing of Hiroshima.  Whether she was actually able to finish is up to speculation, but either way, her efforts are remembered by many.

I don't know if I really believe that I'll have a wish granted if I fold 1000 of them.  But I do believe that the level of dedication, perseverance, and joyful effort required in folding them all will be helpful to a marriage, as well.  On top of that, the strings of cranes are beautiful, and a single folded crane looks an awful lot like a flower.
