well acting is a metaphysical assertion of the physical act of theft, in Cartesian terms: a part of the extension is stolen, for example an object passed down via generations, your grandmother's wedding ring... acting is in a sense a theft that defines creating a civilisation and eradicating tribalism: galoshes, guttering, sewers and irritable bowel movements.*
some said acting was a subtler form of defining theft, given the term doppelgänger; i.e. i stole your shadow, all you have is a hand to mimic a shape of a hare's head to please children, deal with it.
