#2 Flashback To When My Mother In Law Wore This To Our Wedding. You Could Also See Her Purple Thong Underwear Through The Material. See Her Hand Reaching Out
This was during the kiss when she grabbed him so she could kiss him. She wore white to one other sister-in-law’s wedding too. The third sister-in-law she approved of so she wore purple. She is no longer in our lives for many reasons.

#6 In-Laws Leaving Raw Chicken In The Sun For Hours
Staying at my in-laws for the week in Northern CA where it’s 85° today. Got home from running errands at 11AM and noticed this raw chicken left out in the sun for who knows how long. It’s now 2PM and this raw chicken is STILL sitting in the sun. Luckily I’m a vegetarian so I have an excuse not to eat any but this is a regular occurrence in this family. I’m scared to eat anything they make

#8 Help – Mil Defaced Our Guestbook Photo!
Hi! I got married this last weekend. My mother-in-law decided to write on my fiancé’s neck on our guestbook photo. It’s sharpie on printed canvas. I was told I should try rubbing alcohol to gently remove the sharpie, but when I tried a small area, it also removed the print underneath. I am at a loss of what to do. Does anyone here have any experience painting on a printed canvas? If I remove everything in the area could I try to paint to give it its color back? Or how I can fix this? I’m upset but determined to fix it so we can hang it up in our home.

#14 The In-Laws Decided To “Prank” Us By Completely Rearranging Our Kitchen
My (M27) wife (F23) and I just returned from a week-long vacation to find our kitchen literally rearranged. We asked her parents just to drop by and feed our rabbits while we were away. Something they’ve done numerous times and are always paid to do when needed- This vacation was fairly needed as I’m in the middle of attending post-secondary and working part-time while my wife works full time and takes care of the house while I pitch in where I can. And after a 4-hour car ride we are extremely thankful for this break and look forward to preparing for another year of endless work. But lo and behold her parents left us another hour’s worth of work for us to even use the kitchen, as a joke. Wife is more upset than I am but it certainly drew an annoyed snort from me which I believe qualifies as mildly infuriating. Pic is just one of several cupboards. Tldr; needed a break, got a break, immediately unconvinced upon return by people we love and are also paying.

#15 My Parents In Law Keep On Using Our Netflix To Watch He-Man And Christmas Movies, And Change Our Watchlists Because They “Struggle With Tech”
My husband shares both his Netflix and Prime accounts with his parents and pays for it. It first started with his parents using his Netflix instead of their own profile and even trying to charge not-included film to his credit card on Prime . He asked them to stop but they say they cannot figure it out so he added a pin and in brackets that it’s not their profile. We thought the problem was solved, but then I noticed they started using mine instead. I hadn’t looked at Netflix for maybe a week and noticed today they apparently had a watch marathon – my entire history & front page is just He-Man, war films and Christmas movies. The algorithm is completely messed up at this point. Needless to say I got a pin now too and a note in brackets.

#16 Sister-In-Law Always Throws Leftover Food Directly Into The Sink
My sister-in-law always throws leftover food directly into the sink, leaving it for my brother or my mother to deal with before bed. Everyone else is too polite to say anything, so they just leave it. The edges of uneaten toast soak up grease and water. I tried to passive-aggressively put it in a bag for her to see, but she still throws it into the sink. I’m just visiting my parents.

This is also just the guest downstairs bathroom which she sometimes uses. The actual main bathroom is 10 X worse. There are multiple pieces of tiny used bar soaps everywhere, 4 body wash, three loofah, and two shampoo/conditioners.
