In Japan, almost everyone can make origami cranes. All Japanese kids learn how to do it.
I don't remember exactly when I first learned it. I just instantly remember how I go about once I start folding a square piece of paper.
It is said that your dreams will come true if you fold 1,000 cranes.
Hiroshima and Nagasaki memorial parks are filled with those cranes to hope for world peace. People also make cranes as a get-well gift for the seriously ill.
I'm sure there is something like this in other countries as well.
Let me know what people do in other cultures and countries!
