As I sat in the waiting room for my job interview, I could feel the exhaustion from my early morning creeping up on me. I knew a yawn was imminent. I tried to stifle it, but as soon as my mouth opened, it seemed impossible to stop. I grabbed a piece of sour gum from the table, hoping it would help me stay alert, but the flavor was quickly overwhelmed by the fatigue. Yawn after yawn escaped me, each one more uncontrollable than the last. Tears welled up in my eyes as I struggled to keep my makeup from smudging. I was afraid I wouldn't be able to stop before the interviewer arrived and caught me with my mouth agape like a fish. The sound of my yawns echoed off the walls of the waiting room, making me feel even more self-conscious. I tried to take deep breaths and clear my mind, but it seemed like nothing could shake the exhaustion that had taken hold of me.
