Arguing can happen to everybody from time to time. The trick to avoid such scenario is to think about the following before saying something you don’t really mean.
Could my opponents be right? Partly right?
Is there truth or merit in their position or argument?
Is my reaction one that will relieve the problem, or will it just relieve any frustration?
Will my reaction drive my opponents further away or draw them closer to me?
Will my reaction elevate the estimation good people have of me? Will I win or lose?
What price will I have to pay if I win?
If I am quiet about it, will the disagreement blow over?
Is this difficult situation an opportunity for me?
…. Make sense huh !?!
