I've noticed that some people speak foreign languages with what I consider to be quite poor accents, but they enunciate strongly. If they are smiling, it almost comes off to me like they are making fun of the language or just pretending they can speak it well. To the point I've laughed along with them before realizing my mistake and cringing.

And then I wonder which of us is more fluent? The one who with the better accent or the one who can more confidently project their thoughts in that language regardless of "skill"? (Probably the latter)
