Witches aren't always girls were I'm from. I think it's more socially normal to consider them as such, then boys are warlocks or wizards, but as a whole we call ourselves magicians and the hedge-witches that didn't attend a proper school are often also Wiccan and in that faith a witch is a boy or girl.
Another version of Earth where you're a story and I'm the one that goes to a magical school.
