Creating A Stranger

All of my personalities are the same.
very simple and easy that you can recognize.
when I walk through the streets,
I use my first face,
and when I find you,
or when I arrive somewhere,
I use my another face.
but all of my personalities are the same,
and the first and second face are just an identity.
something screams in my skull
"don't come around with a hidden identity."

i hope there isn't any third and fourth.
because this creature lives forever !
