The key to dealing with confrontation between yourself and another is to always remember to remain calm.
Explain to the person that whatever your dispute, it can easily be resolved if the two of you can simply sit down together and talk it out. Continue to stay calm as you assure them you have only love in your heart for them and that you wish them only the very best. Share all these things with them in an open and friendly manner so that they can follow your example.
Once your efforts have been rewarded and the tension that was between you has dissipated, you are now free to exploit the opportunity and punch the person in the face as hard as you can before running away. Just remember to do it calmly.
Calm is key.
