I can relate to that happiness in own space. Although I have a busy life with work, marriage and kids, I also like it when I'm just left alone. Not much of a talker here too.

My partner also has the need to ask questions about my day and expects me to make a long story of it with all the details. But I keep it quite simple every day :D I don't know, I'm just simple.

Still, I can also relate to the NVC in a relationship. There are discussions in a marriage where partners don't listen to each other while arguing. Both try to find arguments to be right. And sometimes you just don't want to be empathetic and just make your point and ignore the other party's feelings, arguments etc. I think there is a lot to learn how to behave and react in family discussions. Although there are many factors influencing your reactions, by practicing how to behave correctly might help you remain calm.
