Hello! So, I'm writing a novel at the moment and I've gotten to a bit that I'm worried might be problematic. So, I put it out for the tropers!
Essentially, the protagonist discovers that humanity is divided across multiple 'worlds'. She is brought to a sort of 'neutral hub' inhabited by people from various worlds.
She meets a nervous, dark-skinned woman who appears to be in some sort of brightly coloured, slightly fantasticaly tribal get-up (or at least she assumes that, based on the fact it's 'weird' by the standards of her own world).
The woman asks her about her tablet computer, and the protagonist assumes the woman is thus ignorant of technology and so explains it in a greatly simplified manner before learning the woman meant specifically what make of computer.
The protagonist, I'll mention, is not white - 3rd generation Nepali American. I don't know whether that makes any difference to how problematic this may or may not be.
