What does the destructive power of boys mean?

This is a stubborn, extreme and dual-character boy. When he is happy, he is full of confidence, sunshine and gentleness. When frustrated, give up on yourself, gloomy and rude! This is also an immature boy! There are many reasons for this personality, perhaps because of the lack of parental love when I was a child; Maybe it's because he 16 years old can't walk through the rainy season! Suggestion: lead him to the sunshine and restore his confidence. If he can come out, he will be a sunny, confident, strong and brave boy!
