The Thing With Many Personailities

Smooth as a shiny mirror.
One big foot with numbers, letters and much much more.
Bumpy as the rocks next to the sea.
It takes me and makes me all different things
I can be a chef
A farmer
A survivor
A surgeon
A soldier
A king
A chicken
A robber
A sniper
A goat
It transports me to different places
It transforms me into different things,
While locking my identity from the eyes of the world.
To take me to these places all I need to say is
SIRI
