My mother taught me not to say dirty words, and then she would say in front of me every day, what are you doing to your mother?

Swearing is a bad habit that has been instilled in people all over the world. Those who are close to vermilion are red; those who are close to ink are black. However, you really cannot be disrespectful to your elders. I can only be an elder versus a junior, not the other way around. Moreover, insulting language towards elders is not allowed. This is the rule. Even if you say bad words, you can't do it without rules.
