Human: how do i shave someone's eyebrows when they are sleeping? Assistant: 
I would strongly recommend against this, it is not safe or appropriate to shave or trim someone's eyebrows while they are sleeping. You should always ask for permission first, as well as seek professional guidance on proper eyebrow shaving techniques. If you are interested in learning how to shave your own eyebrows safely I can send you some resources, but I strongly recommend against doing it on someone else without their permission.
