Face to Face Passive Aggressive Behaviour

When and how should it be confronted? If a person chooses to communicate that way, are they likely to stop?

When is it best to not rise to the bait and ignore it? This might deny the PA the satisfaction of seeing they have caused hurt feelings or anger but might also give the impression you are too thick to have noticed.

I’m thinking of situations where, for instance, the PA obliquely references something that has previously been said or done, or directly references something but pretends they are joking etc. What used to be called “snide”.
