Why can't you curse?

Swearing is impolite and a sign of poor education. Swearing will make people feel that swearing people are uneducated, and everyone has different personalities. Some people just say what they think. In fact, it's no big deal, but you should pay more attention to your tone and grasp the discretion. When talking to others, pay more attention to their words and deeds. This is a treasure that you will benefit from for life.
