I have noticed that there is a moment when I become anxious that another person does a particular thing. At that point my values rate the doing of that action above their happiness and our mutual relationship. I also value it above my own contentment, because it vanishes there and then!
Having lost my contentment it stays lost for quite some hours. Person x probably loses their well-being too.
To be fair often other people go through the same process of demanding certain behaviours from me and finding that their ease disappears too if it is reliant on my compliance.
