Thoughts about conflict is dependent on the topic. Some are more serious and others can be let go easily.
I don’t like conflict. I have to waste too much energy, especially if it can’t be solved immediately.
To me, conflicts are stupid if not solved in due time. Not stupid because of the thing that caused the conflict in the first place has lost value but because the biological and psychological elements of the conflict itself looses value as time goes on.
Having conflict for years without making efforts to try to mend it is stupid. If you try to make things better and the other person ain’t having it, the conflict is on them. You tried. If you are the one that isn’t budging, you really are a bit idiotic.
