I can't understand either, I will never leave my children with anyone i don't know really well (i know some of you could say you'll never know even with people you know perfectely), My children are going on holidays to my parents house and for the moment that's all ! They are still young, and we'll see later, but if someone weird like MJ was asking to spend a bit of time with one of my kid, (if the child is a fan etc ... it's hard to say no), but i think have good time in his property and with his "little disneyland" is enough i think and i'll be present ! I'll never leave one of my kids alone with him ! And even if you don't talk about really bad things could happen to a kid, I think it's just strange some parents leave their kids spending a night with an adult ...
