I feel that your parents are weak and seriously lack self-esteem and self-confidence. I feel that others look down on themselves and hold their heads up in front of others. So always please others. But people who lack self-esteem and self-confidence will show arrogance, so your parents will lose their temper, make noise in front of their families, or show indifference and numbness. However, this character of parents is formed for a long time and cannot be changed for a while. You should fully understand your parents' personality weaknesses, and don't confront them head-on, let alone haggle with them. You should consciously overcome the influence of your parents' personality and strive to be a self-confident, self-disciplined and self-reliant person. If you have made great achievements in your study or work, your parents will think you are disgraced, and even enhance your self-confidence and self-esteem.
