• Maybe you will only be angry with those who you think are not stronger than you, nor capable of hurting you.
• This means that people often vent their bad tempers to those who they think are closest and will not hurt them, and when facing someone stronger than you, you may often put down your temper.

For example, you will be impatient with your mother who cares about you, and tolerate or even smile at your leader who criticizes you.

In this regard, I want to say, don’t always leave bad temper to the person who loves you most.
