I think a lot of people here are missing the point.
Let me tell you a story.
Wednesdays, my friends and I go to the bar to hang out. We grab some beers and some wings, and we have a bit of a chat about, y'know, whatever. Sometimes we're around because someone just wants some company. Sometimes we're around because someone just wants to gripe about something going on. Sometimes we're there because... well, some Wednesdays we're there just because.
And, y'know, it makes me happy to be around when people want to hang out, for whatever reason, because we're friends and that's what friends do.
But sometimes, maybe, I could just as well go home. Like, I'm not opposed to the idea of going: If someone wants to get something off their chest or just really feels like hanging around having a laugh, I'm more than happy to be there with them. But nor, particularly, do I care about being there this particular Wednesday, except for the other guys.
Don't get me wrong: Some Wednesdays I really don't want to go, I've had a shit day at work, I didn't sleep well, and I just want to go home and lay in bed with a book until I crash. Those days, I'll just send a message saying that I'm not up for coming out tonight, sorry.
On the other hand, those nights where I could take it or leave it, I don't really want to send a text saying "hey guys do you want to, maybe, cancel this evening? like, I don't wanna not go, but y'know, I don't want to go either?", because that sounds like some tedious bullshit. And if anyone who didn't particularly give a shit had to announce to the world every time they did not, in fact, give a shit, we'd all get over that really quickly.
The fact that I don't care for sending that message (or receiving a bunch of them either) doesn't really mean a whole lot, in and of itself: It just means that I end up going out more frequently than is, I guess, 'optimal'. And this isn't a problem that needs solving, because eating a couple of wings when I otherwise wouldn't once every two months is hardly a herculean struggle for me, but solving that minor coordination problem isn't exactly an act that devalues my friendships in any way.
Maybe it would make Wednesdays at the pub a little bit more special, because you never have the nights when no one is particularly excited about being there.
