Bad manners refer to behaviors that are considered impolite or disrespectful in social situations. This can include actions like interrupting others while they speak, not saying "please" or "thank you," or using inappropriate language. Such behaviors can create discomfort and tension in interactions, making it difficult for people to communicate effectively. Common examples of bad manners include talking with a mouth full of food, not holding the door for someone, or failing to listen when others are speaking. These actions can negatively impact relationships and social dynamics, leading to misunderstandings and conflicts among individuals, families, and communities.
