Forgive me if I’m wrong but isn’t the maid in the context of the witches simply a hotel cleaner? So I’m not sure what the implications are here?But a maid is entirely different from a cleaner and implies many things, maybe the kid might not know, but he can google it.
Once you change it, you can never google it, and you lost meaning.
Also do you want a sub ten year old Googling “a maid” - I’m sure they will love all of the maid outfits on sale
