What My Mother In Law and Ernest Hemingway Have in Common

A while ago my mother-in-law gave me a box as a present, to keep my pens in.  On its side is a quotation from Ernest Hemingway.  I think it's a pretty safe bet to suppose that my mother-in-law is not a big Hemingway fan, but this sentiment obviously struck a chord with her.  The inscription read:

THE WRITER MUST WRITE WHAT HE HAS TO SAY, NOT SPEAK IT.

Please don't all slap your foreheads in synchronized despair, but only recently have I come to realize that she was telling me to shut the hell up.
