Neither is this:
And no way in Hell can this ever be seen as nice:
*shivers* (I'm going to get nightmares about this post.)
To allow others to see the contents of your mouth is just incredibly horrifying. Surely there are civil laws that say that one reserves the right to sue for that sort of social disturbance. And are there any religious scriptures that urge their followers not to yawn openly so as to cause others displeasure? I mean, look at the utter monstrosity, sitting beside Tony Blair, in this photograph:
The yawn is a strange physiological reflex that just doesn't have an explanation. Researchers hypothesize that yawning might be a method of cooling the brain physically, or perhaps calming the mind psychologically. Yawning might also be due to a lack of body sugar, or a lack of oxygen, or on the contrary, an overload of oxygen.
We yawn when we're tired, and when we're sleepy. Some yawn when they're stressed, but I've never been overworked to the point where I yawn. In my yawning experience, I do it when I'm bored and a lot of people, as I'm sure you know, believe that yawning is contagious. I actually yawned a total of seven times while I was doing a lil' research for this post. Yup, reading about yawning can cause you to yawn too (those of you who did, please say so in a comment :D)
The infectiousness of yawning can prove to be a bit annoying. I was having dinner with my family tonight, and just as I dug into my soup with a spoon, I looked up to see my lovely aunt yawning like a lion. The oh-so-transmittable yawn hit me, and, oh, yes, a little soup dripped out of my mouth.
But my goodness, the way she shut her eyes so intensely as if she was shone on with the light of a million fairies, created this effect of time passing by so slowly, to the extent where I could've counted the number of teeth she had.
Oh, but I did see her uvula, and you don't get to see another person's uvula everyday. That's special. Well, I think so.
Anyway. I like to cover my mouth with both hands when I yawn. I don't think any of us have exceptionally pretty guts, and I mean, the mouth is the beginning of the digestive tract if you think about it. So conceal your oral cavity because somewhere out there, there are millions of people suffering from those nightmares I mentioned earlier on. Well, maybe not millions. But you just never know.
