A well-meaning mum's best intentions fell hilariously – and her daughter let the whole world know about it.
Hanna De Castro, from Houston in the US, recently tweeted a picture of her mother's hairstyling fail.
Pro tip: a "half up half down" hairstyle is supposed to involve the top half of the hair (up) and the bottom (down).
Not, as Hannah's mum thought it was, two different sides of the head.
Twitter loved it, and it turns out Hannah's mum isn't alone in her mistaken understand of this hairdo basic.
In fact, there are quite a few parents out there whose strong suit is most definitely not styling hair.
