Passive aggression is incredibly common. We’ve all been subjected to it and we all use it. Gossiping, backbiting, being late, sulking, are everyday examples. In depression, it’s fairly easy to identify resistance, scorn, hostile, bitterness, and sarcasm, all of which may or may not be wrapped in humor. Passive aggression is a form of anger, sometimes so subtle that it’s hard to spot, even for a trained therapist.
