(Hate is such a strong word...)
The telephone thing. INFPs who never want to make or take calls argghhh. I now have a special way to call that I have to use whenever I want to call one INFP friend at home so she knows it's me. (Ring twice then hang up and ring again).
That passivity might be less annoying if it wasn't accompanied by the aggression that flares if I fail to negotiate the eggshells. It's like crawling over cut glass to make things ok again when she is inevitably offended by something I said. (Not what I said, the way I said it, argghhh x 2).
I think it comes down to the INFPs I know actively looking for the personal criticism in everything. It's a buzzkill.
