Snakes in her head

This will come as no surprise to many of you, but women have snakes in their head. Even me. No, no, it's true, I do. Just the other day....Well, never mind. Let me give you the condensed version of a relationship my daughter has had with this girl for a few years. The girls is a year younger than Pete, but they got along alright for a while. The parents were a little creepy. I should stopped letting Pete hang with them when she went out to dinner with them and didn't come back for 6 hours. Anyway, last spring the two of them were riding their scooters down the hill, after being told to put helmets on. The girl fell, Pete flipped over her, bunches of scraps, and one f'd up helmet. Being the Guiltinator, I pointed out the big scrap and expressed my happiness that it wasn't the little girls head. I told her mother I thought the girls arm was broken, and sure enough, the next day they take her to the doctor and it is. Ever since then, any time Pete has called or walked up to her house to play she has been told the girl is taking a bath or cleaning her room. At all hours of the day. The girl wouldn't return phone calls. I finally tracked the mom down and asked her if something had happened, if my daughter had said or done anything. Oh, no came the reply. We're just always so busy. Right. I tell Pete that for some reason their parents just don't want them to play, it's a shame and their loss, but also their right. The two of them still see each other at afterschool care, sometimes sitting together. Then the girl starts telling Pete her mother says she not a good friend, her father won't let play together, that she's not being invited to the birthday party because she is a "poopy-head". I tell Pete to stop talking to her, tell her if she has something nice to say, okay, but if not, to leave her alone. Then, Pete says she wants to play with the girl at her house, she was invited. I said, not until I talk to the parents. This was about 3 weeks ago.
Did I say this was the condensed version? :)
So, today the girl shows up wanting to know if Pete was "coming to the party, it's right now." Fine, Pete's upset, really doesn't want to miss the celebration. I tell her, Have the mother call me, we'll talk. I'll be damned if she didn't finally call. (Although I suspect it was more because of a poor turnout than a desire to d O the right thing.) I told her what I thought- Pete had been trying to be friends, she'd been rebuffed (baths and bedrooms) and if something had happened I needed to know. She said, oh no, we've been busy the last two weeks. I don't know why Pete's not here, she got her invitation last week (uh, no), I explained some of the things this girl had been saying. In a nutshell, I gave her the chance to tell me to piss off, apologize, whatever. She
lied instead, and then tried to make me feel bad (Well, I guess it's just up to you if you let her come, whiny like) What-fucking-ever!
Look, you don't like my kid, okay, your loss. But don't lie about. This little girl is already playing head games (she's in 2nd grade, now) That's a learned behavior. Fucking snakes in her head, I tell you.
