The Mystic Adventures of Dorian

Five hours after placing the ads, Dorian's phone rings. When he answers, he is greeted by the deep raspy voice of Buttercup, a chain smoker in her fifties.

Buttercup always wanted to learn how to play the piano ever since she was a little girl. She loved to watch her grandmother, also a chain smoker, move her fingers along the ivories.

Deciding that there's no time like the present, Buttercup asks if Dorian would like to start lessons right away, warning him about the smell of smoke.

What does Dorian say?
