RSVP stands for répondez s'il vous plaît and is the time-honored manner in which decent persons let a host know whether or not they will be attending an event. It means "please reply," and it's used on everything from embossed Martha Stewart wedding invitations to Facebook events, like a friend's BBQ or dirty 30 birthday in Vegas. Millennial moms are inundated with invitations, from mommy group events to baby showers to birthday parties. Yes, we're busy ladies, but grown-ass moms always find the time to RSVP.
I have planned enough celebratory affairs to know how important it is for guests to indicate either their plans to attend, or their sincere regrets for being unable (or unwilling) to attend. I am a stay-at-home mom to a toddler with two part-time jobs, and I always f*cking RSVP. I just find it terribly inconsiderate to do any of the following: show up without any sort of notice, say you're coming and then fail to show, or choose not to respond at all. I understand wanting the freedom to "see how you feel" or "play it by ear," but when it comes to planned events, there comes a point where you have to commit.
You know you have a problem when a host leaves the location off the invitation so guests have to get in touch if they want the address. (True story.) It's about time we got it together as a society and held people accountable for the most basic etiquette. Why not start with bringing sexy back to the RSVP?
