Aggressive and Harsh tone of voice; angry; vengeful.
Step-by-step explanation:
Being assertive is simply standing up for yourself while keeping your emotions in control. This can be as simple as, "No, I don't want to". Giving reasoning behind your answers is completely your choice. Aggressive communication on the other hand is any communication that displays anger or can be threatening. The line between these two types of communication can be as simple as your tone of voice, i.e. whether you are yelling or talking calmly, or through language and behavior like cursing/swearing, clenched fists, etc.
