I am more than ready to get under the sheets and fall resting. My eyes are starting to close and I cant stop yawning Im so tired! I stretch, then open my mouth as wide as possible and let out a huge yawn: and you can see every hidden corner of my pretty pink mouth as I do so, my tongue, my whole throat widening, my soft tongue. Be careful when watching this little clip: yawning is contagious! And you might find yourself getting sleepier and sleepier by the second!
