No-one else replied? I was hoping to read answers to this!
I am somewhat in the category you describe. Child of immigrants, barely taught their language. As a result, missed out most importantly on real conversations with older relatives, who are all passed now. They could speak english, but it wasn’t the same.
Still, trying to learn the language now. No-one to practice with - the rest of my generation wants to speak english anyway, my parents speak english to us, as they always have.
Challenges attempting to learn when younger - some particular parents laughed at their children’s efforts, perhaps they didn’t mean to be mean, but it didn’t feel good!
There were others, but i’m hoping someone else sees this and adds so it’s not just me rambling on.
