Aren't you happy to have friends like this? =P
Just last week, i received this letter from a dear friend back in singapore.. and with it, a blessing steming from an ancient Japanese folklore
"An ancient Japanese legend promises that anyone who folds a thousand origami cranes will be granted a wish by a crane, such as long life or recovery from illness or injury."
However, like a typical student doing maths (or in this case physics).. she had to dissect this legend by..
1000 x cranes = Big wish regarding "world peace" or "cure for cancer"..
therefore..
1 x crane = 1/1000 of a big wish, approx enough for wish regarding small things like "exams"..
=X
i had a phys test last sat..
...And i think it helped xD
