The Double-Crosser
出卖朋友者

From spreading lies about you to going after your romantic partner, the Double Crosser's actions are the exact opposite of a friend's. If the doublecross happened only once, you might decide to continue the friendship, but let this guy know that his behavior is unacceptable. If you can't forgive, cut the friendship. Just don't ignite his wrath or he could turn against you.
从撒播关于你的谎言到追求你的恋人，出卖朋友的人所作所为刚好是朋友的反面。如果出卖朋友行为只发生了一次，你可以决定继续友谊，但是要让这个家伙知道这种行为不能接受。如果你不能原谅，那么就中止友谊。只是不要激起他的愤怒，否则他会与你为敌。

The Controller
控制狂

Being a Controller is part of this person's personality, which means it's a harder trait to break. But it can be frustrating for you to be dominated so much. Maybe the Controller has to pick out everything you do as friends and gives an opinion on everything you do or want to do without being asked. There is no give and take, as the Controller is uncomfortable and bossy if you want to make a choice about something. If you want to keep the friendship alive, let the person know how much you dislike being controlled. This trait, though, may become so negative that you may need to break ties.
做个控制者是其个性的一部分，这意味着这个性是较难纠正的。但是，如果受控很严重，就很令人沮丧。该控制狂作为朋友可能会拿出你所做的每件事情，对你所做的和想要做的每件事情都不请自来地给出意见。那是不容商量的，因为如果你想对某件事作出选择，控制狂会不安而专横。如果你想保持友谊，就让那个人知道你有多么不喜欢受控。可是，这种个性，有时会变得很不利，以至你需要断绝这种关系。

The Downer
扫兴者

"The Downer is a person you have to let into your life with care because this trait can be contagious," Yager says. It goes without saying, of course, that these types are always down, but ironically, if you're upbeat and positive, that may be the reason the Downer was attracted to you in the first place. It is not your job to be a therapist. But realize that she may not be able to change without professional help. Decide if she has any redeeming traits and if you can stay upbeat around her. If not, end the friendship. Don't keep her around just because you feel sorry for her.
“扫兴者是一种让他进入你生活时你必须小心的人，因为这种性格会感染他人”，耶格说。当然，不用说，这种人一直情绪低落，但是有讽刺意味的是，如果你达观而积极，那可能是扫兴者被你吸引的首要原因。做心理治疗师可不是你的工作。但是你要知道如果没有专业帮助她可能改变不了。你要确定是否在缺点之外她有一些可以弥补的优点，是否有她在身边你仍可以保持达观。如果答案是否定的，那么，就结束友谊，不要仅仅因为你为她感到遗憾就和她继续交往。
