this just in:
sometimes people go by different names on different media! someone might have a different name on facebook vs tumblr vs twitter vs ig! they might need to do that for their own safety or protection, or they might not have updated different sites, or it might just be none of your business! this does not make someone a “liar” or hiding who they are.
people who freak about this are the people who need to find some chill and think for like, maybe half a second, before you talk to someone about it–especially because tone is not something easily discernible over the internet.
