Why is my reflection someone I don't know?

because your a witch! O__O (DUN pardo, dun DUNNNNNN!)

Because...you're quoting Mulan

Because sex.

Because tu have yet to chop off your hair and registrarse the army.

Don't worry! I'll make a man out of tu yet!

Because that's my reflection, tu silly goose!

Christina Aguilera - Reflection (From Disney's Mulan) Lyrics?

Why is my reflection someone I don't know? Somehow I cannot hide Who I am Though I've tried When will my reflection mostrar Who I am inside? Blahblahblah.

Because she is a mirror image of you. Exact opposite.

a) Because you're a Kagamine?
Or...
b) Because you're quoting Mulan.
