Do 당신 think its shallow to use someone to get to someone else?

Absolutely-especially if the person didn't know they were being used. If they were helping the other person it's a bit of a different story.

Yep, it is. But it works most of the time...

I kinda used someone before once my bf cheated on me & i wanted to show that b*tch how it felt so i used someone but i told him i was using him so it was all fine...
....but if he didnt know he was being used i dont think it means i would be shallow if he didnt know, it'd just mean they're a big fat lying 암캐, 암 캐 is all..not neesarily the lack of knowledge
