After the son came back， the father asked him： “You have thrown the letter in the mail box？”

“Certainly.”

“You have not seen on the envelope not to write the address and the addressee s name？”

“I certainly saw nothing written on the envelope.”

“Then why you didnt take it back？”

“I also thought that you do not write the address and the addressee， is for not letting me know that you do send the letter to who！”

有一天，父親讓八歲的兒子去寄一封信，兒子已經(jīng)拿著信跑了，父親才想起信封上沒寫地址和收信人的名字。

兒子回來后，父親問他：“你把信丟進(jìn)郵筒了嗎？”

“當(dāng)然。”

“你沒看見信封上沒有寫地址和收信人的名字嗎？”

“我當(dāng)然看見信封上什么也沒寫。”

“那你為什么不拿回來呢？”

“我還以為你不寫地址和收信人，是為了不想讓我知道你把信寄給誰呢！”
