Have you ever met somebody who didn't seem quite human?
I recently rewatched the video of the woman on the plane screaming that the passenger beside her wasn't human and it got me thinking about something I've seen.
I remember seeing a teenage girl in a small food store I go to address the guy behind the counter as 'human'. "Thanks, human." Stuff like that. I think she was just doing a bit or something but I thought it was strange.
have you considered that you might be on the autism spectrum? 50% basing that off your description 50% basing that off your username. Normies hardly read xkcd
