Some people do care about what the others think of them and some do not. Usually, the ones who don't care say that they "don't depend on social opinion" - they do whatever they want to do and act a way that may be not accepted by many people. And so, they say that the main mistake of the ones, who care is something like Dependence on social opinion.
Is there in English some special word or word combination for this "dependence"? Like "Social addiction" :D
After reading comments I got, that maybe there is no special word for this situation.
Again, I'm not talking about disorder or abnormality - this is usual behaviour of most people. When we don't do something "stupid", because we think - "Omg, what will people think of me". We don't try to get to know a girl on the streen - "Omg, that's so stupid - if she refuses me, I'll look so stupid".
Usually, so-called PUA (pickup artists) use this word - "Guys, the main problem is that you do care what the others people think of you. You aren't free" - and so on. In Russian language there's no special word - just "social dependence". I thought, maybe there is some special word for the situation, but seems that I was wrong.
