When Korach organized a rebellion against Moshe Rabbeinu, accusing him of assigning power unfairly, Moshe suggested that they wait until the next morning for a sign from Hashem to determine who was right. After each group would bring a ketores, a fire would come down from heaven and burn the offering of the either his group or Moshe's group. He wanted to wait so Korach would have time to think and hopefully, he would change his mind.
We see how important it is to wait a little bit when someone is angry. A good resolution can't always be reached immediately because when people are heated, their emotions take over. Once some time passes, even just one night, it may be possible for both sides to hear each other more openly and logically and work towards a peaceful compromise.
May we be able to give people who are really angry time to calm down so we can keep all of our interactions peaceful!
