I don't know you anymore

I look into the mirror and smile;
My face smiles, right back
I lift my arms and wiggle;
So does she, right back.
Her body swaying to her own beat
Enjoying music that she loves.
I raise my lips to giggle,
But she beats me to the punch, with a laughter completely unfamiliar to myself being honest.
It's like two strangers living together, with emotions that will give birth to a thunder,
I feel her innocence with no armor.
When I look into the mirror
I don't know you anymore.
It's the same person, but just not the same anymore.
I know the girl is truly me.
If not, would that smile seem familiar to the girl I used to be, and those eyes filled with distant memory so clear?
I look into her heart to realize we are still one;
We keep running from the pain,
The truth is hard to see.
But what I wouldn't give to see her face again.
