rsvp'ing

Presented by Seattle Public Library, Friends of Waterfront Seattle, Seattle Office of Arts & Culture and Seattle Art Museum, “Reflections” is free to view, though RSVP’ing on the event’s Facebook page is recommended.

So keep RSVP’ing for one as needed, and share the reason freely when asked: “She’s a homebody,” “She’s tucked in, and sends her love,” etc.

My question is about the etiquette of RSVP’ing to some events.

Would a simple phone call RSVP’ing ‘no’ been better?”
