You say you agree, but your actions say otherwise
When given a task they don’t really want to do, a passive-aggressive person might appear to agree (sometimes even enthusiastically), but they won’t fully comply with the request, Daniel K. Hall-Flavin, MD, explains to Mayo Clinic. Instead, he or she might express anger or resentment by failing to follow through or missing deadlines.
You’re angry but never say so
Saying you’re not mad when you’re actually seeing red won’t do anyone any favors. “Denying feelings of anger is classic passive-aggressive behavior,” Signe Whitson, a licensed social worker and childhood therapist, writes in Psychology Today.
