This story is about the two friends were walking through the desert. Around their journey they had an argument in which one friend slapped the other one in the face.
The one who got slapped was getting hurt and without saying anything just wrote in the sand
“Today the best friend slapped me on my face.”
They both were still walking until they found an oasis, where they decided to take a bath. The one who had been slapped got stuck in mire and started drowning but the friend saved him. After getting recovered from drowning he wrote on a stone
“Today my best friend saved my life.”
The friend who had slapped and saved his the life of his best friend were asked him;
“When you hurts earlier, you wrote in the sand and now, you write on a stone, why?”
The other friend replied;
“When someone hurts us we must write down into the sand where winds of forgiveness can erase it away. But, when someone do something good for us, we must cut or carve it in stone where no wind can ever erase it.”
Moral of the story:
Don’t put values on those things which you have in your life. But value who you have in your life.
