communication

Good morning! A quick question – I am in the middle of the Calmness section in the TSG online course. I just watched the lesson on the four types of communication: aggressive, passive, passive aggressive and assertive. It was so helpful (and entertaining) to see you and your son Quinn acting out the different types of communication! My question is, if someone completely ignores another person or gives them the silent treatment (meaning, the ignoring goes on for days or even weeks) – what kind of communication style is that? Passive or passive-aggressive? Thank G-d, this is not a behavior I am confronted with these days, but I was just thinking over past experiences and wondering how to define it.
