Singing in the Mirror

I hear my daughter singing last night and I realize it is coming from the bathroom. I let it go on for a while but she doesnt come out and she starts to sing in different voices and tones. I found it interesting so I went into look. She was standing on the corner in front of the huge mirror and the cabinet mirror turned so she can see multiple versions of her self in the mirrors. I say "what are you doing" she says "im singing with my girls"! Oh she makes me laugh everyday!
