Two friends were walking through the desert.
During some point of 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 saying anything, 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
had been slapped, got stuck in the mire and started
drowning, but the friend saved him. After the friend
recovered from the near drowning,
he wrote on a stone: "TODAY MY BEST FRIEND SAVED MY LIFE." The friend who had slapped and saved his best
friend asked him, "After I hurt you, you wrote in
the sand and now, you write on a stone, why?"
The other friend replied: "When someone hurts us,
we should write it down in sand where winds of
forgiveness can erase it away. But, when someone does something good for us, we must engrave it in
stone where no wind can ever erase it."
