Why don’t I feel embarrassed? lol?

So I guess my coworker decided to make fun of me behind my back. Everybody was in on it and no one was supposed to tell me. I knew it was going on but I didn’t care. She revealed things we talked about and that’s what they were laughing at. I guess they called it a corporate punishment. Now that they know that I know they’ve stopped. People say I should be embarrassed but I’m not lol.
