If they react with hostility, you should quietly try to resolve the situation with equanimity.
You must refrain from saying anything wrong. Keep the matter inside you and restrain yourself in your speech, whether you are at home or outside.
No one in this world has a right to tell you anything, unless you are at fault.
Even before the person appears in front of you, you have to communicate with the Pure Soul (shuddhatma) within him.
If the words are going to be hurtful, then they should be spoken with humility and respect.
If you talk to a child there should be no hint of authority in it.
You should point out your child's mistakes by explaining things to him rather than intimidating him.
At home you should only give advice when it is asked for. To give advice that is not requested God calls egoism.
If you have harsh speech then you have to use additional words like, I request you to..or I am asking you to please do this much.
Words can soothe or aggravate a person. Therefore, they are all effective. All effective things are inanimate. The Self is beyond effects.
