Threatening to slap someone in the face or using hurtful words can be considered emotionally and verbally abusive behavior. Such actions can cause emotional distress and harm to the person on the receiving end.
Justifying the behavior by saying she experienced it herself when she was younger does not make it acceptable or justified. It's important to break the cycle of abusive behavior rather than perpetuating it.
If you feel unsafe or uncomfortable with your mom's behavior, it's crucial to talk to a trusted adult, such as another family member, a teacher, a school counselor, or a friend's parent. They can provide support and help you address the situation appropriately.
Remember, no one deserves to be treated with violence or emotional abuse. Seek help if you feel you need it, and don't hesitate to reach out to the appropriate authorities or support systems available to you.
