A story tells of two friends who 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, she 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 her friend saved her.
After she recovered from the near drowning, she wrote on a stone:
"TODAY MY BEST FRIEND SAVED MY LIFE"
The friend, who had slapped and saved her best friend, asked her, "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 the winds of forgiveness can erase it, but when someone does something good for us, we must engrave it in stone, so no wind can ever erase it."
