So when you do a French braid in hair, you start off with three small sections. Every time you fold over the outer sections, you incorporate more hair into those sections. This differs from a normal braid, which doesn’t increase the size of the three parts of the braid as you go along.
French braiding flesh would require a lot more flesh. Also it wouldn’t look nearly as tidy because the other ends of the flesh (those not in the braid) are not attached to anything (i.e. a scalp) so it would be a loose tangled mess.
There’s easier ways to make something grotesque and cursed.
So there are situations where it wouldn’t be appropriate to be openly vulnerable. Like in the middle of class, standing up and telling everyone your past trauma. That’s not an appropriate time to share.
But if the people you were with just didn’t want you to be open and vulnerable, that’s on the people, not you. It’s better to be surrounded by people who accept you and are willing to hear your truth.
