That rule isn’t universal though. “I go to the dentist every year” doesn’t imply that I particularly care about a specific dentist (or, case in point, about the specific dentist).
“This was a nice evening” is also difficult to characterize as not caring about which evening it is. As are books titled “An Introduction to XYZ”, where both the authors and the readers will probably care about the specific book.
I'm going to the bank, the shop, the dentist, the pool - I have a regular one in mind and you may well also know which one I mean.
I'm going to a bank, a shop, a dentist - I've found a new one and I may well be about to describe it to you.
"A nice evening" - there have been ones before, there hopefully will be again, this was one of them.
Sure, but that’s different from “you do/don't care which one”.
“Care” may not be the correct word, but in those examples the difference is whether you are referring to a specific instance, or any instance of a group. When you say “I went to the doctor,” you did in fact go to a specific doctor (or “I will go to the doctor” meaning you will go to one). It would be equally valid to say “I went to a doctor”, it’s just less specific.
I believe it is food for thought — would one ever say "this was the nice evening"?
Here it only sounds OK if you make the adjective stronger ("this was the nicest evening", though you'd probably avoid "nice" in this case and go with "best", "most amazing"...), or drop the adjective altogether ("this was the evening").
So nuance is that you might have many nice evenings, with this being one of — but what if you do not, and all are actually terrible except for this one? I guess with proper pronounciation of "THE nice", it can still work (we already talked about nice evenings and not-nice ones, so it'd be "this was the nice one"), but it'd be pretty awkward.
“At the start of the year, my crystal ball told me that all my evenings this year are going to be bad except for one. This was the nice evening.”
Yes, exactly the example I put in ("the one") — thanks for sharing it and showing it might not even be awkward!
Well, on that note: the construction “I went to the store” has always felt wrong to me as a native speaker. People say it even when that store lacks definiteness in context (ie the listener has no reason to know which one you mean). At the very least, it counts as a separate usage of “the” that doesn’t follow the usual pattern, like when you say “the bigger they are, the harder they fall”.
Edit: Here's a frustrating HN thread where someone tried to claim it makes sense, but it turned out his argument hinged on "well obviously all native English speakers regularly go to some store, right?" Screw the homebound.

Looking at: https://advice.writing.utoronto.ca/english-language/definite...
I think the usage falls into this group: "The first group consists of nouns which refer to shared knowledge of the situation or context...",
When you're talking to people you live with it is true that they know which store you are going to. Friends and neighbours would have also have known up to fairly recently, when people still mostly walked for groceries and such to the few small stores nearby and made friends with people who lived close.
So, I'd say it's a bit of a colloquial hold over from walking times and construction taking a listener into confidence.
>When you're talking to people you live with it is true that they know which store you are going to.
But again, people use this even when I have no reason to know which store they went to.
I’m not necessarily saying they should stop doing this, but it’s clearly not the usual kind of definiteness implied but the use of “the”.
It is common for someone to say, for instance, "I need to go to the store" even if they don't have any particular store in mind.
A prescriptivist pedant might insist that this is incorrect, and they should instead say "I need to go to a store", but in my judgment as a native speaker, the version with "the" is more idiomatic, and the version with "a" sounds stilted.
Beyond that, there are cases where you absolutely are referring to a specific one, but use a/an.
"Our house has a pool" for example. There is a very specific pool being referred to, but it's sufficiently indirect that "the" would never be used here without radically changing sentence meaning.
I understand this mostly as "our house is one of a set of houses with pools", which is what anybody cares about in this sentence.
It's like saying "our house has a roof" — very similar, but nobody really cares about the roof, the focus remains on the house.
This doesn’t count because the determination of which house you mean is not based on previous context, but only on the sentence itself.
"I go to the dentist every year" implies that you have a usual dentist or some sort of stable routine or plan vs "I go on a trip every year" which implies the journey is yet to be selected/defined from a multitude of options.
So I feel the rule isn't always taken literally, but the vs a is selected based on whether something is up for consideration/substitution rather than something that's well defined and specified.
Maybe it must be considered from the perspective of the speaker. He may have a particular dentist in mind when he says "the dentist" and maybe the listener not having privy to it may not be relevant.
And he may be saying "a" about the word "nice" instead of about the word "evening".
Note: This is just my opinion and an attempt at trying to make sense of it. Purely subjective take as I usually refrain from making purely opinion based arguments.
No matter how much we try to make objective statements, they are never based on "full, provable truth", and are thus opinions. Conversing with other humans is exchanging opinions based on their own previous knowledge. Thus no need to — when conversing with non-malicious people — state that your opinion is, in fact, your opinion. I appreciate it for what it is, and if I am curious about the basis for it, I will inquire more.
All of the above is in my opinion, but I never state that and assume a good faith reader will take it as such (here for demonstration purposes only :)).
So in short, thanks for your opinion, and I agree this is the largely the basis for choosing between an indefinite and definite article, also opening them up to inquiry ("I am going to the store" — "oh, which one?"; compare to "I am going to a store" — "what are you getting?").
