I sit and work on my laptop, but I feel very tired. I try to resist yawning because I know that once I start, I won’t be able to stop, but the urge to yawn is stronger. I can't resist. I start yawning loudly, my mouth is wide open, and my nostrils dilated. My yawn is deep, and it fills my eyes with tears. I stretch, desperately trying to awake my body and shake away the drowsiness. But yawning overwhelms me. My throat is pink, and my mouth opens wide as I inhale with a loud sigh. I yawn deeply and contagiously.
