　　Say your Facebook 'friends' list count is 500. If you let your own instinct to do some work, it'll help you strike off 450 of them in no time. I hope some of the following signs will help you identify the pretentious ones from the remaining lot-

　　假如你Facebook上有500个好友，如果你跟着直觉走，立刻能排除掉450个人。我希望下面的预兆中有几个能帮你从剩下的一大批人中找出不是真朋友的人。

　　1. Ask for help.

　　1.寻求帮助。

　　Text them but don't tell them what kind of help you need. Just ask them to meet you. When you do that, most of the pretentious ones will assume that you need money. Or something that they don't want to lend. They'll try to avoid the meeting as much as possible. This is when you'll realise how creative people are at making excuses.

　　给他们发短信，但不告诉他们你需要什么帮助，只让他们跟你见面。这样做大多数假朋友都会以为你要借钱，或者找他们帮什么他们不想帮的忙，他们会尽量避免见面，这时你会发现人们在找借口时多有创造力了。

　　2. Notice how often they break their promises.

　　2.注意一下他们是否频繁违背承诺。

　　You see, it’s not necessary that a person who wants your companionship may also want your friendship. If he/she keeps canceling plans over and over, maybe they just wanted your company but found something else to fill that void.

　　你懂的，一个人需要你陪也不一定是想跟你做朋友。如果他/她总是放你鸽子，可能他们只是想找你陪，但又找到别人填补空虚了。

　　3. Do they make you look bad in front of others?

　　3.他们会让你在别人面前出丑吗?

　　It goes without saying that the friendship is worthless if all the fun in it is at the expense of 'your' ego and self esteem.

　　如果友谊中所有的乐趣都是以你的自信和自尊为代价的话，那不用说这份友谊已经没有价值了。

　　4. Jealousy - the two faced ones.

　　4.嫉妒——两面派。

　　Your pretentious friends will always try to undermine you. Your accomplishments make them insecure.

　　假朋友总会在背后诋毁你，你的成就使他们不自信。

　　5. Where they are when you're down.

　　5.你失落时他们在哪儿。

　　Your true friends will stick by your side even when you have failed miserably at something. If they're making fun of your failure or using the occasion do boast their own success, strike them off the list.

　　甚至在你失意时真正的朋友都会坚持陪在你身边，如果有人嘲笑你的失败或利用这个机会来吹嘘自己的成功，赶快把他们踢出你的朋友圈。

　　6. Conveniently friendly?

　　6.自私的友好?

　　You can easily spot the difference in your pretentious friend's friendliness. It'll dramatically increase whenever they want you to do something for them, and amazingly diminish whenever they don't want you to do something for them. They treat friendship as a convenience.

　　你能很容易地发现假朋友的另类友好，他们想找你帮忙时就格外热情，不想找你帮忙时就特别冷淡。他们的友谊只是为了自己方便。
