A pet peeve: People who RSVP to events by saying, "This is my RSVP," or, "I am RSVPing," and leave their response at that, nothing more, drive me insane.
RSVP means, "répondez s'il vous plaît," i.e., "please respond." When you say, "I am RSVPing," or, "This is my RSVP," you have technically responded but neither in the affirmative nor in the negative. Tighten up. Are you attending or not? Give me a yes or a no. When you don't answer an invitation clearly, I want to CYTD.
