A sibling borrows your shirt without asking. A roommate eats your piece of cheesecake. Sure, a lot of us communicate by email, text and twitter these days. But when you really need to get your message across to a thieving roommate, family member or co-worker, the old-fashioned pen and paper may be the most effective--and sometimes the most hostile!

We all know that sharing your home with other people can be maddening. That's why it's so important to laugh about it once in a while!

Do you have any good stories to tell? Have you ever left an angry note on the fridge? Have you ever been the subject of such vitriol?
