"She even acted her own character, and so well, that she did not know it to be precisely her own."

Every nerve and muscle in Rosamond was adjusted to the consciousness that she was being looked at. She was by nature an actress of parts that entered into her physique: she even acted her own character, and so well, that she did not know it to be precisely her own.

George Eliot, Middlemarch, Ch. XII.
