Hal hated Charlie, everything about him, from his knowing sneer to his rolling swagger. When he saw him enter the restaurant with Keith, he wished fervently he could get away and considered getting up and walking out of the breakfast meeting, without a word to either of his two former partners. But then he garnered his faculties and decided to accept this reality. He would choose how to respond, and his choice would be to be cordial and cooperative. He felt a surge of strength as he realized that handling himself in a dignified manner with both these men would be a bigger personal victory than if he met with Keith alone.– Excerpt from The Hero’s Choice: Living from the Inside Out

This passage gives you a little insight into emotional maturity. Hal’s immediate reaction was to simply act out his negative emotions. Instead, he made a decision to respond in a more positive (emotionally mature) way. Notice how that decision resulted in a shift in his emotional energy.
