Snooping in your family member's room is never a good idea, and this Reddit thread explains why.
A Reddit user asked parents to share the strangest things they found in their kid's room and never brought up again. Parents, kids, siblings and cousins all responded with the strangest answers. This is why people need boundaries!
We had to move our kid out of a bad living situation. She wasn’t in any condition to help. So wife and I go in and just start grabbing her stuff. We come across her adult baby fetish gear. Like two duffel bags of it, giant onesies, binkis, diapers etc. Wife looked at me, I looked at her, we shut each bag and have never spoken of it again. - browncoat47
When my late husband was 21, and we’d been dating for a year, he had an MRI for something concerning, and then went back to work ... leaving his worried-about-his-MRI mom from up north (who was just there for his medical stuff) in his apartment alone with nothing to do. So she cleaned. A lot.
