Accumulated frustration and impasses.
For example some problems can't be solved alone and when people are made aware that they are fucking each other because of X reason the logic thing to do would be to stop doing it.
But often people don't and there are various reasons for that.

People are out of our control and we should just agree that we can't and shouldn't control others.
