Yes, it should have alerted you that whatever you were saying to the GM, he did not appreciate it or want it.

Ruby, wasn't everyone aware of your crush on this GM, including HIM? Being overtly obvious about your crush on a professional superior is going to get you into trouble. Perhaps the GM was more receptive to other people expressing that they will miss him, but not to you because you had an obvious crush and it probably made him feel very uncomfortable around you.
