Why We Yawn

Next time you're with a group of your friends, try this out. Take a big yawn, don't forget to cover your mouth, and wait to see how many other people yawn. There's a good chance your yawn will be contagious. In fact, before you even finish reading this story it is likely that you'll yawn at least once. Not that I'm trying to bore you, but just reading about yawning will make you yawn.

Yawning doesn't always mean you are bored. Adelie penguins actually yawn as part of their wooing ritual. Couples face each other and the males stand with their beaks wide open and face towards the sky.

As for why people yawn... good question. Nobody really knows why we yawn. For a while scientists believed that you yawned when there was too much carbon dioxide and not enough oxygen in your blood. Part of your brain realized this and triggered you to yawn. As your mouth stretches you inhale deeply, sending a shot of oxygen to the lungs and into the bloodstream. That theory went out the window because nobody can prove it.

The reason yawns are contagious? Power of suggestion perhaps. If you're out late with your friends after school, you're probably tired. You're probably on the verge of a yawn, too, and seeing one person do it is enough to drive everyone to yawns.

Have I made you yawn yet? If I have, I hope it's not cuz you're bored, but simply by the power of suggestion.

I'm not quiet sure what's a real friend and what's a fake one anymore. I know when there's a friend who's only a school friend rather than an 'outside' friend as well, but at the same time it makes me so confused. Here's my story: There's a girl named Xian. We had a unique way of becoming friends ... but it clicked. For the whole year I've been trying to keep in contact with her ... but she's not very willing to try and put in any effort to stay in contact with me. Her personality is beyond sweet, and her skills at art are even better. If she was to have an award, it would be a giant trophy with her face plastered on it and big bold letters listing 'Nicest Girl In The World!' ... Its just ... she lied to me.  I was all about this friendship. I was ... i'll admit ... sort of a lost puppy following around her owner.  So, I got her this T-Shirt she really wanted for her birthday, and not long her birthday was mine, April First. I was expecting at least a letter, or maybe even something cheap. It didn't really matter to me.  But on my birthday she didn't even come to school. Nor when she got back did she ever say sorry, or give me any be-lated gift of any sort.  That should have been my first clue. Even my mother started catching on. My second clue was she even told me she was oblivious and wasn't good at keeping in contact. I thought she was joking. How could a friendship so sweet be tossed out just like that? My third one was near the end of school, one of her friends in elementary was bragging about the plushies she got from Xian. Apparently she had four from her.  Xian had originally told me it was AGAINST her religion to give out gifts to other people. I knew she wasn't lying about her religion in general, because I met her mom on a field trip and she was quiet ... different. But I didn't understand why Xian had gotten so many small plushies for her, and yet not a single small stamp for me? My last clue was the last day of school. She didn't even try to say good-bye or even hang out with me for that matter. I know what you're thinking. "Girl, you've gotta be kidding me if you can't see that she has no intention of being your friend!" But this girl was the nicest to me. She stood next to me during harsh times, and comforted me when I was down. She told me I was important.  And you don't get many friends to do those special things to you. It was rare to have a friend make me feel so tall and worthy.  ... So ... I can't understand ... why'd she do all that .... and suddenly ... just ... walk away ...
