that's true why do we need to care about what others feel.. right? i also don't care what they say I'm happy as long as my life is what i want

I think you do care and that is the whole reason you wrote about it. Yeah,most times, all opinions are gray. But, we just need to figure out which ones we decide to listen to and which we don't. Most times, you need to communicate. why do you think it's wrong? this is why I didn't think much of it. and if they still don't listen to you or try to understand your perspective. then you can't actually do anything. but you atleast tried. Also, you need to try understanding their perspective as well. Communication works both ways.
