This is sad. Her mom needs a good talking to. Does she understand that not ALL people are good? I would never let my children run the neighborhood. It's not safe. Not that you are a bad person Ivy, but does she even check to see where she is?
I cried for several months after a girl next door was taken out of her yard. Her mom left her to play with some older kids, but they all went home. A convicted and newly released child molester picked her up and raped and killed her. My youngest didn't set foot in the yard for a year atleast after that by herself. I know it made her crazy, but I felt we were in a relatively safe neighborhood before that and it really hit me hard. It could have been MY child snatched away forever.
I know it has to be annoying, but for the child's safety, someone should look into her roaming.
