“The only words you'll regret more than the ones left unsaid are the ones you use intentionally to hurt someone”

Simplified Meaning:

Hurting someone with your words is something you will truly regret. Imagine you have a friend, and one day, you get really angry and say something mean on purpose. Later, you feel terrible about it because you can't take those words back and they hurt your friend deeply. It's often better to hold your tongue and choose not to say mean things, even if you're upset. In real life, people often regret saying hurtful things more than they regret not saying anything at all. For example, if you argue with your sibling and call them names, you might feel bad about it later because it damages your relationship. It's important to think before you speak, especially when you're angry, so you don't say things you'll wish you hadn't. Being kind with your words can help you avoid feeling regret and maintain good relationships.
