Who gives in first

This is a classic discussion strategy in the game theory. There are many points of contentions in day today life. Like between two companies for negotiations, or between a married couple for some house chore, or between parents and child for a toy or something, or between boyfriend and girlfriend, or just friends for ego. All these have just one question...”Who gives in first?”
As per game theory you need to show that you are not affected by the outcome of the deal and this enhances your position as a successful negotiator. However the arguments should not be dealt with arbitrarily either as it would hamper the chances of any possible negotiation itself.
You need to show yourself as strong candidate, but at the same time you should come out as interested one as well. This will keep the opposition on backfoot, as well as involved with a possible solution. It’s a tricky line to toe, but a worthy one beyond doubt.
