Awesome and usefull write-up! For people who like this topic there is a usefull book on Non-Violent Communication (NVC)

Fairly inexpensive and to me it's worth every penny and not only because it lays out step-by-step how you could communicate better; it also has the abbility to make you understand why you formulate words the way you do....

So here are the ISBN numbers :
ISBN-10: 189200528X
ISBN-13: 978-1892005281
