Aggressive: Doing what serves you with no respect for others – “We are going to THIS movie. Why do you even want to see that one?”
Passive-aggressive: Communicating in a cynical way – “Great, let’s go to THAT movie”
Assertive: Stating your beliefs or preferences while respecting others’ – “I’d love to see a movie with you, but not that one. Can we pick one we both like?”
You choose how you communicate.
