When my oldest was in first grade, she decided she wanted a bob-type haircut. She had long hair and wanted something different, so I took her for a haircut. We stopped by NAM's house after, and my oldest was on cloud 9 and so happy with her new look.
NAM took one look at her and went apeshit. She told me that I should have consulted her about getting my child's hair cut because "as many times as [I] have run a brush through her hair, [I] should have been asked before you did this."
My poor daughter's face showed that her little bubble of excitement had not only burst, but it had been shit on.
Fast forward 5 years--and we were living in GA. My oldest put a spray in her hair that made it have a bit of a "summer glow" to it in the form of simple highlights. She was 11, and all three of them were visiting my parents for a few weeks over the summer. NAM asked my oldest if she put something in her hair to lighten it. She became enraged when she found out what happened.
You see, to someone like her, hair is a big deal...even the hair on someone else's head. She must be in control of it at all times, and should the owner of said hair decide to change it, then she must give her approval first. It's really her hair, only it's on another person's head. That's it. That must be how it works. The other person is very much like those foam heads that display wigs. No person underneath at all. Just a shape the hold the hairstyle.
I cut the bitch and the rest of the family out of our lives not too long after that. I didn't find out about this little episode until a few months later when I promised my children they'd never have to go back. They started unloading all kinds of stories that they'd been sworn to secrecy not to tell me. Things like her hitting them, talking bad about me, etc.
Hair. It's not like it grows back or anything...
