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 oasis, where they decided to take a bath. The one who had been slapped got stuck in the mire 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 erase it away. But when someone does something good for us, we must engrave it in stone where no wind can ever erase it."

     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：“为什么我伤你之后，你在沙子上写字，现在却把字刻在石头上？” 他回答道：“当有人伤害了我们，我们应该把它写进沙里，宽恕的风会把仇恨抹去。而当有人为我们做了好事，我们应当把它刻在石头上，没有风可以将它抹去。”
