How can peace prevail? For peace, you have to understand dharma (religion, one's duties, moral code of conduct). You should tell everyone at home, "We are not each other's enemies; nobody should have quarrels with each other. There is no need to have differences of opinion. Let us share with each other what we have and let us be happy." That is how you should think and do everything. You should never quarrel with people at home. How can you quarrel with people you have to share the same home with? Nobody has ever been happy by making others miserable. We want to be happy by giving happiness. We can only be happy if we make others happy at home. You will be served a good cup of tea with a smile, if you avoid conflicts using this understanding. Otherwise, they will ruin your tea before they serve it to you.
