Anon: Do you girls hear that jazzy music playing or is that in my head?
Rachel: I like jazz *proceeds to play air piano to an imagined melody*
Anon: Imagined, huh? What about you, Linh?
Linh: I know nothing about jazz *proceeds to give a very longwinded lecture about the history and subtleties of jazz*
Anon: That's great ladies, I'll just leave you two at it *goes home after finishing long shift with (imaginary) jazz playing*
