I am wondering what "we wouldn’t know anywhere" means in the following sentences:
‘Such fond memories of Brighton,’ Mum is saying to Hannah. ‘You know, I performed down there a couple of times.’ Oh God. Not long before she starts telling everyone about that time she had penetrative sex on screen for an arthouse film (never got a release, probably now on PornHub).
‘Oh,’ Hannah replies, ‘we feel a bit guilty about not getting to the theatre more often. Where did you perform? The Theatre Royal?’
‘No,’ Mum says, with that slightly haughty tone that creeps into her voice when she’s been shown up. ‘It’s a little more boutique than that.’ A toss of her head. ‘It’s called “The Magic Lantern”. In the Lanes. Do you know it?’
‘Er – no,’ Hannah says. And then, quickly, ‘But as I say, we’re so out of the loop we wouldn’t know anywhere, even if it’s the place to go.’
- Lucy Foley, The Guest List, Chapter 14
This is a thriller novel published in 2020 in the United Kingdom. One hundred and fifty guests would be gathering at some remote and deserted fictional islet called Inis an Amplóra off the coast of the island of Ireland to celebrate the wedding between Jules (a self-made woman running an online magazine called The Download) and Will (a celebrity appearing in a TV show program called Survive the Night). The day before the actual wedding day, during the rehearsal dinner, Jules sees her mom, who once worked as an actress, talking to Hannah, who lives in Brighton, about how she used to act at a theater in Brighton. (The narrator here is Jules.)
In this part, I am wondering what "we wouldn’t know anywhere" means, especially as to what "would" means here.
Would it be all right to understand that "wouldn't" here implies a hypothetical future where Hannah will hear a theatre (which is a must-visit place) and she probably will not know anything about that place?
I am wondering how it is different in saying just "we don't know anywhere" and saying "we wouldn't know anywhere" in this dialogue.
