1.See what happens when you refuse them on multiple occasions
1.看看各种情况下你拒绝他们会怎样。
2.Ask something of them as well, see if they refuse or accept
2.也向他们提出一些请求，看看他们拒绝还是接受。
In all of the above, look at their reaction, see if they care or that you did that for them or not, or if they were annoyed that you couldn’t do it.
在上述所有情况下观察他们的反应，看看他们是否在乎你帮不帮他们的忙，或者你做不到时他们是否会生气。
Also, think. How often do they ask you of things? Wold you rather do something else instead of helping them? When you see that person, are you annoyed?
而且你要思考一下，他们多久向你提一次要求？你宁愿做点别的也不愿意帮助他们吗？你见到这个人会生气吗？

They always take, always ask, and never do the same back to you.
他们总是索取，总是要求，却从未给你回报。
They may be nice, polite, and nice to be around. But you will never ever get the same from them. Also, it may be the only time you hear from them or see them is when they want something.
他们可能人很好，有礼貌，很好相处，但你从他们那里永远得不到回报。而且可能只有当他们有要求时才会跟你说话或见面。
Those are some of the indications.
以上都是暗示。
