Thinking about how great the music for Dr Seuss's The Lorax animated special was and how some parts of it still make me cry when I hear them
When the Once-ler explains what an Unless is at the end, even though it's maybe ten seconds long, just, ;~;
You can just /hear/ how hopeless things are by how everything is presented and the music backing that scene accentuates it perfectly
Honestly that whole story still gives me chills though :s it's almost like they were warning us in 1972 and nothing has changed at all
