She's 17 her sister is 19. Lots of talk via snapchat amongst some boys in her year that her sister is "stunning" and she is the "downgrade".
She got to hear about it and went right up to the wee shit who had called her the downgrade and said
"So I hear I'm the downgrade, huh?"
He blustered about just the fact that her sister is stunning and that he didn't mean she was the downgrade he just said it etc etc
So she says
"Tbh I think that says more about me than you. I mean, you can't even get the downgrade. What kind of a skank are you."
"What do you mean I can't even get the downgrade? Who says I can't get the downgrade?"
"I do. This downgrade says she wouldn't touch you if you were the last boy on earth. Consider yourself burned"
And walked away (apparently to yeowwwws of approval from his two friends)
I am cringing, but I'm also proud of her ballsiness.
