When you disagree with someone today, you will have to be the one who puts things right again.
You will have an argument or disagreement today and you are going to have to put things right, whether you were in the wrong or not. Be the bigger person and talk this through calmly. You will have the chance to explain your position, but do not let this descend into conflict again. Make sure you patch this up face to face, or the risk of confusion will be high.
