Very random thought I had at school today-
Ok, so, when Percy swims in the river styx, he becomes entirely invincible except for the small of his back right?
If that's true, then how does he cut his hair?
Or is he just not able to?
And then my brain went on to Percy trying to cut his hair, and then Annabeth comes in and is just like 'what are you doing?' and Percy responds 'trying to cut my hair!' and she sighs thinking he's js being stupid and goes to help him, and the scissors break when she tries, and they just spend hours struggling trying to cut Percy's hair before eventually giving up.
