Bathroom Drama

My friends and I were at school, which has been deemed extremely haunted. Anyway, we all decided to go the bathroom around our first break time (around 10:00).

Our building, the Annex, has had unusual sightings before. It was not my first time to see something spooky in our school. While we were in the bathroom, the mirror was already foggy. We suddenly saw an S on the mirror. We proceeded to scream. I was still calm then. When we turned around, we heard something in one of the cubiclets. Then we saw a pair of shoes identical to mine. But we didn't see anything else. Just shoes. Then we looked back at the mirror, another letter was already forming. We all screamed this time and ran out.

We haven't went to the bathroom of our school since...
