Like everyone else, I had trouble with the definition of "fluent". I said 1, because there's really only one language that I feel like I could immediately jump into writing with minimal recourse to reference material. But that seems like a bad definition, since I could very quickly increase that to 3 or 4 by just brushing up on a few languages I haven't been using much lately, and I could increase it pretty much indefinitely by spending a week or so with any given C-style language.

On the other hand, maybe that's not enough to truly count as fluent, in which case I plausibly am not fluent in any language.
