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.

Is there someone you can tell? Like a parent or some other adult? What do you expect us to do?

What's the difference between emo and goth? :confused I wouldn't know I'm awful when it comes to stereotypes although mean girls and the DUFF have been very educational.  My style is meeeeee :love the style that always changes. But I have always been an outcast, so I'd rather just be a loner or something.

Sixteen and Twenty-one? Ah nah. This isn't okay at all. I think your parents or you should tell her parents. This is the only way.

While engagement isn't illegal for juveniles, marriage is as you can already tell. Judging by your feelings, I don't think the relationship will last long enough for him to be able to wait. I heard some courts will allow it, depending on location. Knowing whether her engagement is okay is a tricky thing. She seems pretty confident in the relationship. As for your own feelings, how well do you know him? Do you have any knowledge about him outside their love life? Do her parents know anything about him? If you don't now the answers, don't be afraid to ask them to her or her parents. I'm also a 16-year-old girl and I don't feel comfortable with it. Many young adults have a hard time understanding the transition from  teen to adult, but if he's put his problems on her, that's a bad sign. I don't think 5 months is long enough in my opinion and I think this could lead to making bad habits in a relationship. I appreciate that you're trying to help your friend be safe. Hopefully some of her closest people will help her with you. They don't necessarily have to steer her against him, but they should help guide her into deciding what's best ad how to carry on from that.
