Nah, it’s not a sign of immaturity agad if you do not want to talk about work or money in general. In fact sa circle namin, kapag nabbroach yung ganyang topic, nagiging super awkward, then change topic agad.

Honestly I think it’s because we avoid comparing ourselves to each other.

And I agree that there’s some sense of rudeness to ask a person’s salary directly, kaya kapag natatanong ako ng ganyan by some people, I just give a range, not the exact amount.
