One day, two friends were walking through the dessert. During some point, they had an argument and one friend slapped the other in the face.
The other friend got hurt and without saying anything, he wrote in the sand...
The two friends kept on walking until they found an oasis, where they both decided to take a bath.
Finally, a nice bath after a long walk.
It feels so good !
While enjoying their bath, suddenly, the friend who had been slapped got stuck in the mire and started drowning.
Holy - I'm coming ! I'm coming! Hold on! please !
Luckily, his friend heard him seeking for help and he quickly grabbed his friend and he was saved. After he recovered from drowning, he wrote on a stone...
After I hurt you, you wrote in the sand. Now, you write on a stone. Why?
When someone hurt us, we should write it down in the sand where winds of forgiveness can erase it away. But when someone does something good for us, we should engrave it in the stone, where no wind can ever erase it.
