This is really interesting stuff. So what this is about is basically creating a variant of an OutputStream that, when faced with a request to close the stream, it asks the user for confirmation before doing so. What we're learning is what to do when we have a class we want to use but we want one small thing about it to operate differently from how the class normally operates.

But I'm sure that will become clearer to me as I progress.
