There is one little girl, lets call her Jane, on the street who I am pretty sure is younger than Princess and she is outside by herself ALL the time. In fact, most of the kids are outside unsupervised. And Jane in particular, likes to come and ring my doorbell 5 times in a row when Bobo is sleeping to ask if Princess can come outside and play. One day, I was making dinner, and she kept coming to the door every 15 minutes. I watched her walk away from the door and there were no other kids outside for her to play with. Its like her parents kick her outside and wont let her come back in, so she is stuck outside board.
I will not let my kids play outside unless I am out there watching them. Princess is 6, she is kinda at the borderline age where maybe she could be outside without me. But mostly I don't trust her not to go into another kids house to play without my permission. Also she is WAY to friendly with strangers, I tell her not to talk to strangers but she doesn't like to listen.
