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.

last friday, i was home alone, my dad went to am AA meting and chiz, so i was alone for a couple og hours, i mean yeah i'm depressed, i cut, i have suicidal thoughts daily.......it's hard hurting inside..and just to see everyone pass you by like you're nothing, people judging you without knowing you. i also have social anxiety, and it really bothers me at school, so i try to walk fast in the halls, and i'm tense a lot. people criticize me once in a while.... ive been through some stuff, i've seen my mom abused infront of me thousand of times..........it's just hard...life. i'm scared to deal with it. so i made a noose, tried to attempt. long story short, my friend called the police, i got sent to the ER......my dad doesn't trust me alone for a mere 3 seconds, cause he thinks as soon as he turns his back i'll cut myself, or hang myself

So there's this guy in my class and he sits next to me. Correction he HAS to sit next to me, So my classroom as a table with 2 desks connected to make a huge desk but separated holders things to put our stuff in. So this guy is really the class clown of the class and he can be a jerk when he wants to be but sometimes can be a really nice guy. He likes to talk to me and he "Occasionally" Touches my hand or arm in a friendly way.. I think :3 but anyways he teases me ... A LOT but he sometimes insults me but when he sees my face not cracking into a smile. he instantly says sorry or didnt mean it like that kind of way and i smile. So does he like me? Or he just being a regular guy?  Ello and I thinks he likes you and feels your the close enough friend what he can joke around with. He doesnt want to offend you or upset you and that shows he cares about your feelings. Me advises is take your time and see how your friendship develops.  If it feeels natural to ask him does he like you then ask him and theres no rush :) Good luck :love
