There comes a point in every young childs life where they go "mum, whats your name?" And then proceed to be agast as she says something like 'Julie' or 'Madeline' and discover their mums name isnt actually 'mum'
They will never use this infomation unless theyre upset and need to pack a punch, so instead of the corny teenager, "SHUT UP MUM" they can deliver that blood thinning "FUCK OFF MADELINE" with some gumption for once in their lives.
