The other day, I read, so called a mail of "mother of my child friend" in a person’s blog.

I don't understand what she wants to say.

- One phase is too long.

- There are a lot of conjunctions in her mail, but the conjunction doesn't work well, for example "However" and "therefore"

- The words "Sorry" comes at the end of the sentence.

Generally speaking, I cannot understand the contents of the mail.

------

However, as soon as my wife read the mail, she could understand the content and teach me it.

At that time, I could find a fact.

""Mother of my child friend" uses cryptographs in her mail."

The mail is going to be decoded and understood by an open key, that the special persons could understand the background each other.

-----

We, in especially, men in the science and engineering majors, keep saying that these mails are "incomprehensible" or "unintelligible".

This is a ridiculous misunderstanding.

Nothing special.

We don't have a decode key to resolve the cryptograph mail.

Who should be criticized are men in the science and engineering majors, who do not have the ability for high information analysis function of the mothers.
