As with many things in life, what works for you may not work for everyone. Some people don't even know what they want to know. In the words of that great poet, Donald Rumsfeld: "there are also unknown unknowns – there are things we do not know we don't know." [1] That said, here's something that works for most people when they get an unwanted call: "I don't want to talk about your product. Do not call me again. Have a nice day."
