"In argument truth is born." The phrase attributed to Socrates is in some ways true, but in others not entirely true.
Sometimes an argument goes nowhere, and often it's because there simply wasn't much point to it.
In order not to waste time, it is worth asking just one question. It will help to understand whether it is necessary to continue the dispute or to simply make peace and not return to this issue anymore.
You need to ask yourself: “Will his/her behavior bother me in a year?”
If the answer is “no”, then the dispute can be ended and reconciliation can be made.
The “yes” option means that you will have to work through the problem that has arisen together with your opponent.
Otherwise, the dispute can develop into a conflict and ruin the relationship.
It will not be possible to simply “hush up” this problem, because over time it will again make itself known and provoke a new dispute.
Only joint development and search for compromises can put an end to this case.
It is also useful to ask this question out loud. This will encourage the opponent to also think about it and decide for himself whether he needs to continue arguing with you.
