Office Etiquette -- How not to be one of "those people"

I sit in a corner cube at work. Aside from the wonderful space it affords me (decorating ideas anyone? I seriously have a lot of gray-fabric-wall here that needs help.), I can also hear pretty much everything that goes on in the bosses’ offices. Normally I just plug in my headphones, because no one likes a nosy Nancy, but sometimes I hear things on accident. It’s not a big deal, but sometimes people feel the need to talk loudly in Spanish. Thus begins the rant:

As someone who speaks Spanish and works at speaking, reading, and writing it properly…I get annoyed when people try to speak Spanish to hide things, which is the only reason you’d do it at work, and then end up doing it poorly! If you’re going to talk (loudly) about people, talk about projects, or just shoot the breeze, do it in a language you can speak rather than speaking an amalgamation of Spanish and English that makes no sense. Or, here’s a thought, you have an office, not a cube, CLOSE YOUR DOOR and talk in whatever language you’d like.
It’s rude. Plain rude. Sure, I can understand everything you’re saying and I know it’s not important, but other people don’t know that. It makes them uncomfortable. What happens when people are talking in a language you don’t speak around you? You get self conscious, right? Duh, you’re human! It’s like when you go to the nail salon and you sit down and immediately the manicurists start chattering in a language you don’t know. So you’re sitting there decoding body language and context clues and you convince yourself that they’re judging you for your cuticle beds, when they’re more likely having a conversation about their plans for that night. RUDE.
It’s unprofessional. This is a continuation of number two, but I like lists better when there are three items. It gives them more weight. Anyway, it’s unprofessional. You shouldn’t engage in secretive behavior at work. You’re perpetuating a clique culture which is never productive. Besides, how secretive is it when 15% of the floor can understand your secret, coded messages?

To be fair, I don’t think I would care as much as I do if it was someone else who orchestrated these linguistic parties. But I don’t like this person much, and I don’t trust her – she’s all about Eve. So kids, don’t be exclusionary, linguistically or otherwise.
