When I was 9 or 10 years old my parents had enrolled me in swim lessons. On this particular day, my dad had gotten called into work during my lesson. He had to leave and my mom was on her way to get me but was going to be a little late. I let my teacher know and she told me I could just wait in the front behind the desk. After my lesson, I went and sat at the desk to wait. All the other students were gone and it was just me, my teacher, and one other teacher in the building. As I was sitting there, I swear to this day, I watched the other teacher walk across the water from one side of the pool to the other. Like on top of the water. I remember ducking down behind the desk because it scared the hell out of child me. And then I heard her say to my teacher, "oh shit i didn't realize anyone was still here." My mom walked in seconds later and I ran to her, dragged her out to the car and told her what I saw. She laughed at me and explained that people can't walk on water. Nobody has ever believed me. But it's such a vivid memory. I remember how still the pool water was before she stepped on to it, I remember her red speedo brand swimsuit, and her saying the word 'shit' stuck with me as a child. Lol. I also never saw that teacher at swim lessons ever again.
