What’s so terrifying that it’ll make high-school students panic like they’re seven and someone just took away their recess?

Apparently, it’s not a giant zit on prom night or the revelation of a secret burn book. It appears that the worst thing on planet Earth is one goshdarn moment without Snapchat.

Kansas high-school teacher and possible Snapchat plant Tracie Schroeder says that she can’t remember anything disrupting her classroom more than the latest Snapchat update.

In 16 years of teaching I can't think of anything that has ever disrupted my classroom more than today's @snapchat update.

What did Snapchat do? Well, yesterday, they finally fulfilled the promise of their name by adding a chat function to the primarily photo-based message service. Not only that, but they also added live face-to-face video chat. Apparently, it was so distracting, that Schroeder had to start taking phones away. And then things went south. Fast.

As she tells Business Insider:

Today was the first day in a long time I actually took phones away. I have no idea what all was included in the update, but you would have thought it was crack. They seriously could not keep away from it. I even had one girl crawl under the table with her phone.

At that point I took all the phones away and we had a little reminder chat about when it was appropriate to use your phone and when it was not. Also that it was rarely appropriate to hide under the table.

For quite awhile now, kids have had a real anxiety about being separated from their phone, but today it was near panic. I am hoping by tomorrow some of the novelty will have worn off and we can get back to business.

Separation anxiety, it seems.

@arainert @hamburger Not confused. Just couldn't bring themselves to put it down. It's a true addiction with some

Teens be lovin their Snapchat. And this little anecdote has to be sweet, ephemeral music to the company’s ears.
