I regret one thing in life, but I blame being a hormonal teenage mess, and would never ever act like this now!
When I was at school, year 8-9 (so like 13-14) we had a new girl start our school. She had naturally bright blonde hair, nearly white. She was put into my class and I was asked to look after her and help settle her in. We were in art class and my year 9-10 bf came into the class (remember having an older bf was a big deal back then) to use some equipment. The new girl was practically drooling over him & asking a lot about him, both me and several other people in the class said that he was already taken. She then came up to me whilst I was on my own, and told me that he wouldn't be my bf for long, and she would get him...
Like I said such teenage drama!
She attempted flirting with him, even pushing herself against him over the next few days, but she got nowhere.
The next week in art class again, she said she was going to do something to make sure she got him ( she did that gross bj thing where you push your tongue into your cheek to make it look suggestive)
I snapped, had enough, so I got fountain pen ink cartridges, and poured them onto her white hair!
She came in the next day still with bad stained hair, and people bullied her for being a floozy and having blue hair. She left the school shortly after.
