Pig Latin and Possible Worlds

Ugh. Today was the worst day ever recently. One of those where all the little things go wrong.

I'm supposed to be writing about Possible Worlds... damn Philosophy. I thought I knew what I thought, thought I had an opinion and could write what should be a short, easy essay about it. Then I started reading.

Which brings me to the point of the entry. On Tuesday I was in Chequered Court, reading William Lycan's chapter in Micheal Loux's anthology about possible worlds. I complained about a large passage of untranslated Latin in a footnote, and the following conversation ensued:

Dave: "Why don't you just learn Latin, then?
Me: "I tried, but my school stopped teaching it after a semester, and switched to French."
Dave: "Wow, that's... sensible. French is actually a living language."
Me: "Of course, I remember more Latin than I do French... but I do know Pig Latin."
Dave: "Pig Latin's not a real language."
Me: "Sure it is."
Dave: "Adding 'ay' to the ends of words doesn't make a language."

Well, the rest of the chapter contained several more phrases of untranslated latin--though these were short enough that I could mostly puzzle them out--and one French phrase, 'façon de parler', which I'm assuming means 'figure of speech'. However, it also contained a full sentence of untranslated Pig Latin--and salient to the point, as well--but fortunately I'm fluent :P

ETA: So... I haven't written anything yet. I've spent a lot of time procrastinating, though, and have learned that
