The story goes 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 felt hurt, but without saying anything, wrote in the sand: Today my best friend slapped me in the face.
They kept on walking until they found an oasis1, where they decided2 to take a bath. The one who had been slapped got stuck in the mire3 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 erase4 it away. But when someone does something good for us, we must engrave5 it in stone where no wind can ever erase it.
两个朋友结伴穿越沙漠，旅途中二人忽然吵了起来，其中一个掴了他们一记耳光。被打的人感到自己受了伤害，但什么也没说，只不过在沙地上写下了如此一句话：今天我最好的朋友掴了我耳光。他们继续前行，看见到处绿洲，他们正计划在那里洗澡时，刚刚被打的人不小心陷入了泥潭，开始深陷，他的朋友救了他。
等他从几近淹死的边缘苏醒过来后，他在石头上刻下：今天我最好的朋友救了我的命。他的朋友问：为何我伤你之后，你在沙子上写字，目前却把字刻在石头上？ 他回答道：当有人伤害了大家，大家应该把它写进沙里，宽恕的风会把仇恨抹去。而当有人为大家做了好事，大家应当把它刻在石头上，没风可以将它抹去。
