How do you respond to someone sharing bad news/situations?

I just stay quiet.

I don’t like to say I’m sorry because that doesn’t feel genuine -its not my fault.

I also struggle with faking concern when it’s a total stranger.

I want to edit: I am not necessarily referring to like “my dad just died”.

I mean like a conflict between two people where one is hurt. It doesn’t involve me, from my perspective the situation is dumb. But I am expected to at least go “I’m sorry you are dealing with this” even though it’s like… but it’s not my problem.

And then I think well, how would I want someone to respond and I think unless I am asking for advice I would just want a listening ear, I don’t want them to talk at all. But people don’t seem to like that either even if they don’t ask for advice.
