Fitting In Cardboard写本专属自己的使用手册When I was younger I had this feeling that there was this handbook that Id never gotten that explained how to be, how to laugh, what to wear, how to stand by yourself in a hallway.在我年纪比较小的时候,我有这个感觉,有这本我从未得到过的手册,解释了怎么做、怎么笑、穿什么、怎么独自站在走廊上。Everyone else looks so natural, like, theyd all practiced together and knew exactly what to do, even just the way that theyd push the hair out of their face.其他所有人看起来好自然,就好像他们全都一起练习过,且确切知道要做些什么,即使只是他们将头发从脸上拨开的方式。My experience was pretty much the opposite: I was conscious of how I sat and how I smiled. But when I was alone with another person, I had no idea what to do or what to say. I could just feel myself panic. It sucked.我的经验是几乎相反的:我知道我要怎么坐、我要怎么笑。但当我单独和另一人相处时,我完全不知道要做什么或要说什么。我会就感受到自己惊慌失措。那糟透了。Id imagine what people were like when I wasnt around: how theyd compare notes on how I didnt quite fit. Or even worse, maybe they just wouldnt notice.我会想像人们在我不在时会像怎样:对于我不太融入一事他们会怎么交换意见。或甚至更糟,也许他们就是没有注意到。So I tried to pick up the patterns. I wore what they wore, and said what they said. I even wrote ;smile more; on a sticky note. And over time it sort of worked in a way. I made a version of me that fit in, whatever that means.所以我试着去学习那些模式。我穿他们穿的衣、说他们说的话。我甚至在便利贴上写“多笑一点”。随着时间过去,在某种意义上有点行得通。我创造出了一个可以融入的版本的我,不管那代表什么。But as I grew older, the patterns kept changing. And I took so much effort to keep learning them. And I was still stuck with the problem that I started with: being terrified at the moment when my tricks stop working.但当我年长一点,模式不断改变。我做了好多努力去持续学习它们。而我还是卡在我一开始的问题:在我的伎俩行不通的那一刻感到恐惧。I think it took me too long to learn something. That even though there is a thing called fitting in, that is something that you can learn and practice. Those pages are so thin compared to who you are. That the way to become natural, like I wanted to be so badly, is by forgetting what youre trying to beat other people.我想我花了太长一段时间去学某件事。即使有一件事叫做融入,那也是一件你可以学习并练习的事。那些书页跟你是谁比起来非常浅薄。要变得自然的方式,就像我深切想要成为的样子,就是要透过忘记那些你试着要打败其他人的事。If there is a handbook, you probably get to write it yourself.如果有本手册,你也许要自己编写。201503/366126

MH370: Family Members Mark One Year since Disappearance马航 MH370 失联一年,家属:“我们仍在等着你。”This is the house of Patrick Gomes, the in-flight supervisor for MH370. Exactly one year ago, he left here for work on what should have been a routine flight from Kuala Lumpur to Beijing, but he still hasnt returned.这是 Patrick Gomes 的家,MH370 航班的座舱长。就在一年前,他离家搭上这班原本应该要从吉隆坡到北京的例行班机,但他仍未归来。Well, you know, when were always thinking of exactly what happened and on that day itself—you know, the conversations we are having, the tears and the hugs that were giving each other, and you know, the phone calls were making to friends to find out exactly whether they know anything, so...its still very fresh in my mind.嗯,你知道,我们仍一直想着到底发生什么事以及想着那天--你知道,我们进行的对话、我们给予彼此的眼泪和拥抱,以及你知道,我们打电话给朋友问问他们是否知道任何事,所以...这一切在我脑中依然很鲜明。A few of the relatives of the missing cabin crew members have gathered at this house to remember their loved ones.几个失踪机组人员的亲戚聚在这间房子回忆他们挚爱的人。Right now, we would like to take a minute of silence.现在,我们默哀一分钟。Heres one of the boards where theyve written some well-wishes, one of them saying ;Assalamu Alaikum, Daddy,; clearly written by somebody whos Muslim wishing peace upon their father. Theres one that says, ;Were still waiting for you. Miss you all.; Its clear that the people who are on board MH370 are very well-loved.这儿是其中一块他们写下一些祝福的板子,他们其中一人说“祝你平安,爸爸”,明显是由某位希望平安降临在他们父亲身上的穆斯林所写下。有一个说:“我们仍在等着你。想念你们所有人。”显然在 MH370 航班上的人们都被深爱着。Shes a very caring person, all right, to what...to what I know for the whole life, yeah. Beside that, shes a...very loving mom for the kids.她是个非常贴心的人,是的,就我...就我一生所认识的,没错。除此之外,她是个....对孩子非常慈爱的母亲。Three-year-old Rafael also misses his grandfather, but Malaysias government is struggling to comfort families. This official, though, says hes doing his best.三岁的 Rafael 同样也想念他的爷爷,但马来西亚政府正努力安抚家属。而这位官员说他正尽他所能努力。Thats why we are really committed to find the truth, to find the closure. And until today, we are still looking to it.那就是为何我们十分致力于找出真相、让此事件落幕。直至今日,我们仍期望着这。This is a tree made up of all 239 cabin crew and passengers on board MH370. This and the event have been built as a remembrance rather than a commemoration. And the distinction is extremely important for the family members, because for many of them, they still believe their loved ones are alive until they have evidence to prove otherwise.这是棵由 MH370 航班上所有 239 名机组人员和乘客所组成的树。这棵树和这个活动是举办来作为一场回忆而非纪念仪式。而这区别对家属们来说极为重要,因为他们之中许多人,他们仍坚信他们所爱的人还活着,直到他们有任何明其他结果的据。201507/387772
