One does not attempt to make sense of the Adventurer class.
One merely accepts what is, and enjoys the freedom.
However, in this case I think reading a magic scroll and writing a letter informing others that there are monsters in the area can safely be described as rather different things.
Just imagine we're in England and the scrolls are written in French, which every member of the nobility learns as a first or second language but few peasants did. It is just some inconsistent wording that causes the grief.
