This is the very argument post-modern philosophers make. It's not that text is meaningless, it's that text has too much meaning.
Without the author guiding your interpretation, it's almost certain that you are mis-interpreting a book.
But you don't have A CONTEXT (one, 1, singular), you fuckwitted doubletwat.
You have TWO CONTEXTS (2, two, plural).
For as long as you have MORE THAN ONE CONTEXT, the meaning of the word 'bank' (as I intended it to be understood) remains ambiguous to you.
Which is exactly what I claimed.
