Thank you for joining and sharing your view point.
The moments where I feel not being understood and still stick to wanting the other one to understand me, the effort often becomes too huge and I realize at one point, that I want it too much instead of let it go.

Right, there is carelessness and disinterest. As long as you sense some remaining interest and care it can have a satisfying outcome, I agree.

Often enough we still kill time, that is also true.
