The Competitor
竞争者

Some competition can be healthy -- if your friend's goals or achievements serve as motivation for you -- but if the Competitor wants what you have, acts in a hostile way and will do anything not only to get what you have but take it away, this could cost you. If your friend has to get a house that's bigger or more expensive than yours to seem more successful than you, it may be time to dump her.
有些竞争是良性的（如果朋友的目标或者成就，能成为你的动力），但是，如果竞争者想得到你所拥有的东西，以一种敌意的方式行事，甚至可以不惜一切手段来不仅得到你有的东西，而且要夺去这些，这可能会让你付出惨痛教训。如果朋友一定要得到一所比你更大更贵的房子，以显得比你更成功，那么可能是摆脱她的时候了。

The Bloodsucker
寄生者

This friend is overly dependent on you for emotional support or information. True, it can be flattering to be needed, and of course, the Bloodsucker may be there for you when other friends are too busy for you. But this energy vampire can be draining, which is why you should consider if this friend is worth keeping. As long as you set limits and know that this person will probably make extreme demands on you, you could keep this person in your life.
这种朋友在情感方面或者信息方面过度依赖于你。被别人需要会让你觉得很受用，这是真的，当然，当其他朋友因为太忙而不能陪你时，寄生者可能会站在你身边。但这种精力吸血鬼会大量消耗你，这就是为什么你要考虑一下，是否这种朋友值得你交。只要你设有忍耐限度，并且知道这种人可能会对你作出过份要求，那么，你是可以与这种人来往的。

The Abuser
虐待狂

Don't tolerate anybody who verbally, physically or sexually abuses you. Of course, in some situations, it can be tough to figure out what constitutes abuse. Keep in mind, if someone is vicious and malicious in their comments and treatment of you, you're being verbally abused. Even sexual abuse may not be obvious, as it include subtle behaviors like making jokes that are offensive or sexual in nature, inappropriate comments or sexual harassment. If necessary, contact local police, counseling centers, victims programs, addiction programs or emergency hotlines for help. Then keep this kind of person away from you.
不要容忍任何言语上、身体上或性虐待你的人。当然，在某些情形下，很难确定怎样就构成了虐待。记住，如果某人言论和谈及你时恶意、不道德，你就受到了口头虐待。虽然性虐待可能不太明显，因为它包括某些微妙行为，如开些无礼或色情的玩笑，不适宜的谈话或性骚扰。如果有必要，可以向当地警局、咨询中心、受害者康复项目，成瘾康复项目和紧急状况热线求助，这会让这种人远离你。
