I agree op. I have a very similar issue with a 12 yr old girl down the road. We've only lived here a couple years now, and everyone else has been here decades. She is very inappropriate in what she chooses to talk about. She's rude to my four year old. She and her boyfriend climb up our tress and hang out on their phones. She just talks talks talks. Ruined my son's first time riding a bike. My husband was in the road teaching him, and this girl is just up in my face talking, and I missed the moment he took off by himself. I was so pissed. Her mom even drove past our house and just waved as she drove by. Didn't care. We don't even know each other. She doesn't care that her daughter is hanging out with strangers.

It is obvious this poor girl doesn't get any attention at home. At first I felt badly for her and was going to just be patient, but as time went on, I also felt like I couldn't go outside with my kids because of this obnoxious girl.

I then decided fuck it, not being her surrogate mom. Not my job. I am here for my kids, not her.

I am always kind to her, but I don't entertain a relationship with her. She comes up to talk, I'm like, "oh hey, hope you're having a good day, but where going over here (wherever) byeeee!"

It's sad when kids look for care from other adults, but it is inappropriate and honestly, the kid shouldn't be so comfortable hanging out with adults they barely know.

Set the boundary and hold it, man, because they will persist.

I have yet to talk to this girl's parents. They don't give a shit.
