情書

從前有個男孩深愛一個女孩,但是女孩的爸爸反對,並希望他們的愛
情就此結束。於是男孩寫了一封情書給女孩,讓她知道他依然深愛著
她。男孩知道信一定會被女孩的爸爸先拆閱,所以他想了一個辦法…
The great love that I have for you
is gone, and I find my dislike for you
grows every day. When I see you,
I do not even like your face;
the one thing that I want to do is to
look at other girls. I never wanted to
marry you. Our last conversation
was very boring and has not
made me look forward to seeing you again.
You think only of yourself.
If we were married, I know that I would find
life very difficult, and I would have no
pleasure in living with you. I have a heart
to give, but it is not something that
I want to give to you. No one is more
foolish and selfish than you, and you are not
able to care for me and help me.
I sincerely want you to understand that
I speak the truth. You will do me a favor
if you think this the end. Do not try
to answer this. Your letters are full of
things that do not interest me. You have no
true love for me. Good-bye! Believe me,
I do not care for you. Please do not think that
I am still your boyfriend.

嘿嘿…夠絕吧…恩斷義絕…不過男孩跟女孩
約定,只看單數行…黃色部份…

SO…各位…回頭再看一遍吧…纏綿悱惻喔…

這與密碼學的原理是不是很像呢?
