I followed her footsteps until they faded into the sound of metal clashing. Before I knew it, she was gone behind a swinging locker room door and on both sides of me were wall-to-wall windows. On my left side, an empty room drenched in afternoon sunlight. On my right, two masked figures dancing and attacking. It was like watching two hummingbirds fight. Tufts of brown hair poked out from beneath the masks and I knew Sadie wasn’t underneath. I heard voices behind me and quickly pulled up my phone to pretend I was texting. Two more women walked past me with their gym bags and through the locker room doors. 12:02 PM. The two figures left the room through a separate door and a few seconds later two more entered. A bead of sweat ran down the side of my face and I wiped it away and rubbed it on my t-shirt. The first figure stopped closest to the door. The second bounced into the room. Their hair was neatly tucked away and soon they began dancing. The first figure lunged at the second. The second stepped to the side and a loud beep sounded. The second bounced back to her side. This continued. The first leading the attack and the second capitalizing on their mistakes. Her tempo was merciless. I don’t know why Sadie told me to come. I don’t know why I told her no and came anyway. I needed an edge. I needed to catch her when she thought she had the control. I needed to find my tempo.
