OK, now I’m going out on a limb here, but I think she bleaches her hair.
(sorry had to - I remember some girls in HS putting that one out there, LOL)
H.S. Girls. Some of them are pure evil! We had the most gorgeous girl move to our town when I was in high school. Obviously some sort of ‘Nordic’ bloodline - she was STUNNING with long, blonde hair, tall, blue eyes. Just a real beauty. Super-shy. Modestly dressed. Not the least bit of a show-off due to her looks, etc.
The current crop of, ‘Alpha Females’ at the time took squirt guns, filled them with ink, then ambushed her and ruined her hair.
I’ll never forget it. I seem to remember them getting away with it, too.
B*tches! I have never gone to any of my HS reunions. Pretty sure I’d punch one or more of them these days, if I saw them again. I don’t think purely mean, jealous and vindictive kids grow up to be stellar adults.
