Turns out one of S's friends who S is very close with hates me. So I'd been asking why I'm so hated.
S's friend read my posts where I wrote about S's parents' visit and the horrible crap I went through. And the friend thought I was out of line and should've been more respectful. And because of that, he hates me.
So to that friend who forms opinions without getting to know who I am, here's what I have to say:
Mind your own business.
