I dunno, I think especially in older generations, the earnest conversation is something to be avoided at all costs. For my dad, that's just how he was raised and I think his worst nightmare would be talking about feelings or something.

So take that and then put a hobby/passion that clearly means a lot to your folks and yeah, those can really combine in unfortunate ways.

Personally, when we're not talking politics (my parents' version of sports) I will sometimes throw more serious or interesting questions at mom (as said, dad hates that so I don't push) and sometimes get interesting answers. It's effort and mostly a one way street but I try to remember they're not from a super healthy emotional era and even if they might at times be open to it, it does not come naturally to them (or me if I'm being honest.)

Don't know if that early morning ramble helps but I hope it does.
