I don't know about you, but I always have to make a sound when I yawn. I had a boss that would get so mad at me for doing this (plus, I didn't cover my mouth) and she acted like I was punching her grandma in the face. She was so personally offended by my "bad manners". I was like, "Listen lady, your job isn't to attack my yawning habits. So back off." My last day on the job I should've walked into her office, stood on her desk, and with my arm raised like a Shakespearean actor, and with great gusto, unleashed the biggest yawn I could've mustered.
ANYWAYS.....lets not go off on any more tangents....
Here are some things I like to do to make a yawn something worth looking forward to:
-add some vibrato to the end. The more operatic the better
-smack your lips at the end like you just ate some yummy pie. Like this "aaaaaahhhhhhhhh...num num num"
-my personal favorite is to throw in a chewbacca noise at the end. It always catches people by surprise
-yawning takes your mouth to its very limits, so while your mouth is stretched as far as it possibly can go, take it a step further and widen your eyes and flare your nostrils. Maybe even add a little shaking so it looks like it's almost painful to get out.
-on the exhale part of the yawn, the "ahhhhh" part, just scream bloody murder.
-inhale: raise both arms above your head while wiggling fingers exhale: lower back down. bow.
Do you have any more ways to make a yawn more fulfilling?
