Don't speak.
Your face says too many words.
Don't give me that forced smile.
I've seen your attempts to look warm before.
Didn't fool me then,
certainly won't work now.
I know that you're not happy here.
There's no need to sugar-coat.
One request, please?
If I may.
I know that you're unhappy.
Darling, please don't stay.
