Вопрос по английскому языку:

Нужен точный перевод

I look into the mirror
And whom do I see?
Somebody that looks
Just like me.
When I smile
That somebody smiles too,
He seems to follow
Everything I do.
I jump and he jumps,
I clap and he claps,
I run and he runs,
I stand and he stands,
And if I run away,
Away will run he.
And do you know why?
Because he’s really me
