In my desperation to help the 2 kids mentioned in the previous post I left out some important information. Sorry guys, it's a little hard to ask for your advice when you don't know all the facts.
The girls are ages 8 and 10
The mom is gone because she works weird hours (at a bar)
I am under the impression that her other kids are supposed to watch these 2
The parenting style next door is very "let them raise themselves"
Thank you all for your wonderful advice, I greatly appreciate it and will let you know what I decide to do.
Ta Ta for now
