Well it depends. I'm not the best at relationship advice, and yet relationship advise about highly sensitive people, I'm an expert in. I think what bothers me is,and I'm relying on INFP, by the way I'm not suggesting every INFP is like this, just so it isn't typism,a lot of people I know in my past are INFP, I've read that INFPs are fragile and are easily hurt, but they won't tell you,you've hurt them, you just got to know. For me as an ESTP, this is just deadly, because I need experiences first hand, and if they're not giving me any hints I've hurt them, then it's like people have given me the nod to keep using my shovel to dig my grave. And for me, that's ultimately what happened. No one told me I was hurting people because I'm disabled, and an INFP doesn't hurt people's feelings, especially not a person with a disability, they're people with special needs, we've got to be nice to Brian, to his face, but then talk to other people about his behavior behind my back. I am just learning that this is just as much their weakness, as they want to avoid confrontation at all costs. So, it's like a double-edged sword, not telling me about your sensitivity hurts me, I don't want to come across as a big bully, but it also hurts them, as they are prolonging their misery by not confronting their own weakness. Sometimes our greatest enemy is ourselves.
One INFP I remember, would say they're a "delicate little snowflake" ,and she said it in a drama queen fashion. So, that's my experience with HSP.
