This would probably be more appreciated on a meme site, but of well, here we go:
Someone listening to other people speaking in a foreign language.
"Oh wow, they are speaking a different language than me."
A native speaker of that language listening to the exact same conversation.
"Hmm, yes, they are definitely from the south of the country. Probably from that village near this and this town. Close to the main road, three houses from the left."
