Scream-a collection of extremely short horror stories

I'm talking to the man in the mirror

I had this ritual for a week before starting my first job that was me, staring at myself in the mirror, and saying " who are you?" I asked this question in the context of what kind of person I was going to evolve to be in society. Then, the day before I started the job, I asked the question and my reflection answered me with " Not who you think."
