A story tells that 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 ON 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 he 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."
