A story tells that two friends were walking through the
desert. At a specific point in the journey, they had an
argument, and one friend slapped the other one in the
face.
The one who got slapped was hurt, but without anything
to say, he wrote in the sand: "TODAY, MY BEST
FRIEND SLAPPED ME IN THE FACE."
They kept on walking, until they found an oasis, where
they decided to take a bath. The one who got slapped and
hurt started drowning, and the other friend saved him.
When he recovered from the fright, he wrote on a stone:
"TODAY MY BEST FRIEND SAVED MY LIFE."
The friend who saved and slapped his best friend, asked
him, Why, after I hurt you, you wrote in the sand, and
now you write on a stone?"
The other friend, smiling, replied: "When a friend hurts
us, we should write it down in the sand, where the winds
of forgiveness get in charge of erasing it away, and when
something great happens, we should engrave it in the
stone of the memory of the heart, where no wind can
erase it."
