Had one of my moms old high school friends live with us for a few months. She had recently gone through a messy divorce involving finding her husband very involved with another man. So my parents let her stay with us for a few months while she figured things out. Over the course of the time she was staying there she would repeatedly clog the toilet and blame it on my little sisters and I. The worst part is there was no toilet paper in the toilet, just pure shit. She would also accuse us of stealing her food even though it was on a shelf well above a place my sisters and I could reach at the time. AAANNNDD she had a "boyfriend" who I think lived in Ireland or whatever and would Skype him very regularly. These Skype calls went the way you would expect it would between two adults in a long distance relationship, the issue is that she never locked or even completely shut the basement door so I would go down to do laundry and whatnot and she'd just be down there spread out in front of her laptop for all to see. Needless to say my mom and her aren't very close anymore.
