"My sister-in-law copied our key and let herself into our house...and I found her escorting her coworkers on a tour of my house, saying, 'Isn’t this wallpaper atrocious?'"

"He had a girl staying there without our permission. Obviously, we were beyond livid. I don’t even know how to describe the rage I experienced. When he got confronted, he targeted me, saying it wasn’t my house, and that I don’t work, therefore I can’t complain, and treated my husband like shit. To this day, I haven’t forgiven that, and my husband lost faith in his own family."

"Six months later, at my wedding, she told my mum that she thought my mum's boyfriend of 10 years was someone my mum had made up because my dad had gotten a new girlfriend. She also told my mum my sibling's cancer diagnosis wasn't a big deal, and that her friend was much sicker. Had I known that's what she was saying to my family, I would have thrown a glass in her face and kicked her out."

"Outside of that, I was home with the flu once, and I woke up to our dog growling (he only growled at my SIL). When I opened the bedroom door, I found her escorting her coworkers on a tour of my house, saying, 'Isn’t this wallpaper atrocious?' Changed the locks that day. It got worse, and she’s the reason we divorced. She’s also the reason he’s on wife number three."

"MIL hung up, and my SIL TEXTED MY HUSBAND. 'You guys are so rude.' One hour passed, and my MIL TEXTED HUSBAND AGAIN, 'We are coming. We will just drop something at your doorstep and leave.' Boy, did this have me fucking livid one week postpartum. LIVID."

"When my mother passed after a long health struggle, and I was drained from caring for her, burying her, etc., she made rude comments about my mother being buried at the VA cemetery because it was FREE. Not because my dad served and my mother worked at the VA for over 25 years, devoting her life to veterans and their families. She is a miserable human, and I just smile and keep it moving."
