Love languages... Don't forget the different dialects and the slang ones. I would propose there are also alien versions, like Klingon... (Sorry, I just couldn't resist.) Now that you're aware they exist, does it change how you interact with your partner? Are you more conscious of the language, its inflection, how it's best expressed? Does that knowledge influence who you really are because, instead of being natural, you consider how to change your responses to ones which resonate more with your partner?

I'm not saying any of it is wrong, but I have to wonder...

If you need to dissect the expression and acceptance of love, to determine if it exists, is it really love, or just an equation?
