Eh, I thought it was funny and didn't overthink it.
I don't applaud after every song. I do after some, but in most cases, I don't like to pull myself out of the story and separate the performers onstage from the character in the story. Sure, big solos, big production numbers, of course, some songs and performances ask for it, but "I'm Not That Girl (Reprise)" doesn't need to grind the show to a halt.
I always applaud at curtain call. I don't always stand.
Like a firework unexploded
Wanting life but never
knowing how
