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, he 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 his friend saved him. After he recovered
from the near drowning, he carved 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 carve 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 away, but when someone does something good for us, we must
engrave it in stone, where no wind can ever erase it."


"LEARN TO WRITE YOUR HURTS IN THE SAND AND TO CARVE YOUR BLESSINGS
IN STONE "

This advice is too complicated... Here is my way: If your friend slaped you, kill him instantly. Put his body in a grave and his memory in your heart. Then carve his name in a piece of rock and put it on his grave. Remember the place that you put the rock so you can go back and rember what his name was once in while...
