Les Mis piano music scoresheet from the library.
The husband was playing On My Own (lyrics here).
Him : Hmmm...which scene was this song from again?
Me : The part where where Eponine realised that her love is unrequited. That she has been friendzoned.
Him : What? What's the word you used just now?
Me : Unrequited love.
Him : No, the other word.
Me : Friendzoned?
Him : You mean they wrote a musical piece hundred of years ago *points to the scoresheets* of this song, and you summarised it with one word - FRIENDZONED?
Me : Yeah. That's effectively it.
The husband shakes his head.
