It's been pretty obvious that humans do not exist in equestria, aside from a few human like objects; like the groucho glasses and the foam finger but what i'm wondering is why don't they add humans into the series somehow? I know a lot of people say it's a bad idea and that it wouldn't fit with the series but what i'm wondering is simply why? I'm not saying it's a good idea nor am i saying it's a bad idea, i'm just really confused on why it's so bad. So, can somebody please explain to me why? Somebody? Anybody?
