社交媒体脱瘾
主持人
今天是社交媒体脱瘾活动的最后一天，布伦顿高中正在为购买新的体育器材筹款。脱瘾开始时，已经有100多名学生被劝说停止以任何形式使用社交媒体，为期7天。这意味着不给朋友发信息，不发照片，不写博客——什么都不做。家人和朋友答应给他们钱，因为他们每天不用社交媒体就可以赚钱。他们很兴奋。他们很紧张。但他们能做到吗？
随着脱瘾的结束，他们打开了设备，又重新上线了。我敢说你和我一样急切地想知道到底有多少人受到足够的激励坚持了整整七天！如有的话，他们从这次经历中学到了什么？
安娜，17岁
我坚持了两天。脱瘾比我想象的更难忍受。我觉得我失去了一只胳膊！两天不吃东西也会比脱瘾更容易！但经过深思熟虑，我可以看出我有多少时间都在忙于查看我的手机。我现在正尽量少花点时间上网，多花点时间重新开始我的业余爱好。
德文，16岁
我坚持了四天。星期一，我和我的同学谈到了我们周末做的事情，不知道他做了什么，真的很奇怪。我们通常本应该发布图片并更新我们的个人资料的。脱瘾意味着我们必须谈谈并解释我们在做什么和在想什么！它让我意识到我已经忘记了真正接触的价值。
辛迪，18岁
我设法坚持了整整一周！一开始，我真的觉得我会错过什么事情。然后，我没有给我的朋友发短信，而是去了她家。没有手机，我们进行了两个多小时的正常对话，没有被其他人的信息分散注意力。感觉真好！然后我决定每天去看一个不同的朋友。到了第五天，我想知道：不经常查看手机，我是不是真的错过了解其他人都在干什么的机会了？
马科斯，17
说起来不好意思，我第一天就认输了！我知道那天晚上有个聚会，但是不使用社交媒体，我记不起它在哪里！最后，我打开手机查看，但忍不住快速查看了一下我的社交媒体账户。更糟糕的是，我后来又花了很多时间去看新闻，差点错过了聚会！
乔治，16岁
我也脱瘾了七天！老实说，我并没有觉得脱瘾太难，但我确实把手机给了爸爸，以避免屈服！我哥哥认为我应该充分利用没有手机的时间，所以他带我去了我们当地的体育中心。(在那里)每天一小时的运动使我筋疲力尽，早早就寝。脱瘾使我更健康！
主持人
这次脱瘾活动总共筹集了1 632.82美元，用于购买新的学校体育器材。干得好，所有参加脱瘾的人！看完这个论坛上的帖子，似乎也有人通过脱瘾筹集到了钱以外的一些东西。意识到我们对社交媒体的依赖程度可以帮助我们远离社交媒体，更好地相互沟通。
