Look, I know it's a stage (usually) and part of their brain evolution but fuck me, the selfishness and self absorption really flabbergasts me sometimes. My dh has had to rush off to help his mum who is having a crisis due to undiagnosed dementia, most likely, and not once have either of my teens asked about how things are going with her!? They're 15 and 18.
In general, they're OK kids in general, and I have been keeping them updated, but that's the only reason they know what's going on. I know there's an argument of "they don't have to ask because you're telling them" but it's only if I seek them out, sometimes later on in the day.
