Hello! This is a legal letter!

In this letter, I assert some unspecific rights, and intimate in broad, vague terms, that you have, or may have, infringed those rights in ways which I have not set out.

I will also throw in some things which are totally lawful for you to do, but tie then in with other general assertions of wrongdoing, just to fill the page a bit.

I now insist that you stop doing the things which I haven't spelled out, or else I'll be forced to take some unspecific action.
