I have a tweenage sister (TS) who told me before that she liked Justin Bieber. I almost cut off ties with her, except I still need her to get me water once in a while.
THEN my brother introduced her Taylor Swift. NOT the first few albums, but the "Look What Made Me Do" Taylor Swift. I almost cut ties with him, except we never meet anyway since he lives in Bangkok.

But this week, when I was home my TS asked me:

TS: Do you know Imagine Dragons?
Me: Yeah, I'm a big fan. Why?
TS: I like their new song *played "Believer" on her mobile phone*
Me: Oooh... my baby sister...
