Yesterday O. was looking in the mirror at his moustache and said, "It's not looking good is it?"
Me: Shawanana wana mummble mummble shwoo shwoo shwoo
O.: Should I remove it?
Me: Honey, whatever YOU want to do, you do.
O.: No really, you tell me what to do, should I remove it?
Me: Yes! Yes, remove it.
As of last night it's gone. Whew.
