Eavesdropping on a conversation without the consent of the people involved is an invasion of privacy and hence not elating but annoying for everyone involved.
Context: Once I was complaining about an annoying client to my coworkers, and when I left I saw she had been sitting outside the door the entire time.
Hypothesis: I was totally elated when I left my office to see my annoying client sitting outside the door eavesdropping on our conversation

Is the hypothesis incorrect? (Yes, no, or unknown)?
