You asked for https://nvcacademy.com/index.php?option=com_k2&view=item&id=1267:using-nvc-when-the-going-gets-rough-saying-no-in-the-face-of-pushback-and-intensity&Itemid=438, and despite looking far and wide we could not find it. What may have happened?
the link you clicked to arrive here has a typo in it

or, quite unlikely for sure, maybe you typed it yourself and there was a little typo?
