Morning came without fail, but today, I pretended I couldn't open my eyes.
The phone alarm was already ringing for the third time. In the past, I would have jumped up at the first vibration to get ready for work. Today, even just staring at the ceiling felt overwhelming.
Mornings after becoming a police officer were always full of excitement. Who could I help today? What events were waiting for me? I was someone who gained the strength to endure the day from even a single smile from a person. I was the one who would playfully put a hand on a colleague's back and laugh, saying, "Let's do our best today!"
Since when was it.
That those words stopped coming out of my mouth.
I forced myself up and headed to the sink. There was a familiar face in the mirror. Only the eyes were strange. Like a room with the lights turned off, eyes that reflected nothing.
After a mechanical wash, I picked out the uniform I usually wore. The ironed uniform was perfectly neat. My past self felt pride every time I put this on. I was proud of the fact that I could be responsible for someone's safety.
But the current me. My hands trembled at the weight of these clothes.
Even the small motion of putting on the jacket made my fingertips stop several times. It felt as if I were draping a boulder over my body, not a uniform.
I stood there for a long time with my hand on the doorknob.
If I go out, I have to smile again. I have to pretend I'm okay. Because Sergeant Rader is always bright. Because everyone believes that.
