Evil Clone

One day I was walking on the street to my nearest mail box. Along the way I saw someone that looked almost like me across the street.

It was weird.

I paid no mind because you know staring was bad. As we passed each other going in our opposite directions I began to wonder.

Where did this evil clone come from?

I dropped the main in the box and proceeded to go home. Hmm,

If she's my evil colone then she would be the exact opposite of me. What kind of person am I? and based on that who would be the evil clone? Me or Her.
