I knew the fearful day would come sooner or later. However, it came too fast. I was waiting in the dental（牙齿的）clinic, nervous about what was to come.
Seeing my nervousness, my parents told me to sit up, and to take deep breaths to keep calm, which worked. However, the peace was short-lived. Almost immediately, my name was called, signaling my turn had come. I pretended to be deaf but my mother gestured at me to stand up. I forced myself to step forward and tripped over a toy left lying around by some kid. My clumsiness（笨拙）got me the attention of everyone in the room.
I had refused my parents offer to accompany me. I meant to show them that I was brave enough to face the difficulty on my own. Thankfully, I forgot my anxiety as I looked around the dentist's room. Tools of different sizes were arranged neatly in a tray（托盘）on the tiny table which was connected to a chair with buttons and a light hanging right over it. I didn't look at my dentist in the eye as I took my place on the chair nervously. I almost jumped out of the seat when all of a sudden the chair moved and I was lying down facing the bright yellow light.
The dentist spoke in a relaxing voice behind her mask. Everything was going smoothly and I was quite proud of myself. Then something went wrong. I was picking up the cup of water placed next to the chair for patients to rinse（冲洗）their mouths when I caught sight of the dental drill. Panic related to a bad childhood experience involving the drill kicked into me, and I spat out the rinsing water, right into the surprised dentist's face. I froze with awkwardness and my mind went blank.

A moment later, I got to my feet and tried to wipe（擦去）away the water on the dentist's face with a tissue.
