I could easily make up my own number-to-letter system, but the chances of it being the same as someone elses is pretty slim.

1 60 407 3453= I do not care. See, you didn't read it correctly, what a decoder you are, geez, you could have had bad guys saying stupid stuff like this and you had to decode it, and they could have killed you by now, what a shame you are to the CIA.
