When I was around 11 or 12, I was best friends with this girl who lived about a half mile away (grew up in a very rural area so us kids just walked through forests to our friends' houses). We did everything together but I wasn't usually allowed to stay the night at her house. Her dad was 'ill' and divorced from her mom so they lived with her dad's parents. When my mom made sure the grandparents were there the whole night, I was able to stay over. For some reason, I wasn't allowed to stay in my friends room and had to sleep out in the living room. In the wee hours of morning, I heard her dad come into the living room and breathing heavy...he was arguing with himself about cuddling and touching me but his other voice kept saying "no! She is a child and a friend of my child, so no!" I was so creeped out I never stayed the night again..
I later found out her parents divorced because of the worsening of his schizophrenia and the wife was bipolar. He was having a conversation with one of his bad voices and luckily her dad was able to suppress it and kept me safe. Still scary as a tween though. Still confused as to why I couldn't stay in her room...her grandparents were very religious so maybe they didn't want us lesbianing out? Who knows.
