I’ve seen “let alone” used on Lemmy a good number of times now and, at least when I noticed it, it was always used incorrectly. It’s come to a point where I still feel like I’m being gaslit even after looking up examples, just because of the sheer amount of times I’ve seen it used outright wrong.
What I’m talking about is people switching up the first and last part. In “X, let alone Y” Y is supposed to be the more extreme case, the one that is less likely to happen, or could only happen if X also did first.
The correct usage: “That spaghetti must have been months old. I did not even open the box, let alone eat it.”
How I see it used constantly: “That spaghetti must have been months old. I did not eat it, let alone open the box.”
Other wrong usage: “Nobody checks out books anymore, let alone visits the library.”
Why does this bug me so much? I don’t know. One reason I came up with is that it’s boring. The “wrong” way the excitement always ramps down with the second sentence, so why even include it?
I am prepared to be shouted down for still somehow being incorrect about this. Do your worst. At least I’ll know I keep shifting between dimensions where “let alone” is always used differently or something.
I parse “anxious to get going” as being overwhelmed in the interim: restlessness, beset by uncertainty (“did we pack the toothbrushes?”, “did we confirm the hotel reservation?”, “what does traffic look like?”, etc.). The eagerness is for the going itself, the anxiety is for the period up to the going.
My wife, for example, is always anxious about dozens of details and considerations in the lead up to a trip, but once we’re actually in the car and en route that falls away. I think a lot of people are the same, where they panic about little details up to an event, but once they’ve crossed the threshold from lead up to the event itself the prep panic disappears.
That’s how that should be parsed, you’re right. A bit of a weak example on my part, because it can and should be understood exactly like that. But typically, in media, that is not the intended meaning that they are trying to communicate.
