<p>Some of this might be based on regional culture as well as individual personalities/circumstances.</p>
<p>IME in the NE, whether someone comes to a gathering/party depends on individual maturity, weather, work/family schedule, etc. </p>
<p>All of those factors in isolation or in some mix can cause folks to not be sure of their schedule until the last minute, to cancel at the last minute, and/or to forget to cancel at all. Most people tend to be understanding of work/family schedules…especially considering many friends and sometimes I myself work very odd hours or are in jobs where we could be called back into the office/job during evenings/early mornings. </p>
<p>Most of my friends and I don’t do RSVPs for the above reasons and because among most friends, it’s viewed as too formal for anything other than a formal occasion like a large birthday party, wedding or something along those lines. </p>
<p>Even using FB’s invitations where RSVPs are provided as an option for invitees, whether someone RSVPs or not is not necessarily a good indicator of whether they’re coming or not. All the friends who have done invites for house parties/gatherings, musical performances, bar nights, etc take the “it is what it is” view and don’t get hung up on whether the RSVP list corresponds with who actually shows up or not. </p>
<p>Personally, once I RSVP to an event, I do make it a point to go unless there’s a genuine last minute emergency…and “I’m too tired” isn’t it. Especially considering I am a bit of a follow set plans once they’re made type so I will make sure I’m not doing anything to be “too tired” or something weak like that on the day of the event. </p>
<p>If I’m not certain I can go to an event less formal than a wedding or birthday party, I’d usually prefer to not RSVP and instead, email/call in advance to let them know that I’d try to make it to their event, but I can’t guarantee it. IME, it’s much better than using FB’s “Maybe” option…especially considering in practice, it seems it’s the same as saying “I’m not coming”.</p>
<p>Ironically, I’ve found like most friends, I have a much harder time feeling able to make commitments once out of college because our jobs are of the type where we could and are often called in to work/office at the last minute during evenings/weekends…including while we’re at a friend’s musical performance, house gathering, or even a weekend BBQ.</p>
<p>At the last weekend BBQ I was invited to which started on a late July saturday early afternoon, within the first 3 hours, 3 out of the first 7 guests ended up having to leave because some emergency developed at their respective jobs and they were recalled to the office. Out of a total of around 20 who were invited, about another 5-7 canceled within an hour or less of the start time for the same reasons. </p>
<p>At the end the host, myself, and 4 other friends were the only ones lucky enough to stick around for the entire BBQ from early afternoon till midnight. Enjoyed some fine German bratwursts and other meats accompanied by a variety of beverages…including two kinds of beer homebrewed by the host and a friend themselves. :)</p>
