I think it's really polite of C-3PO to talk to other droids and things in human-language. Higher throughput, lower error protocols must exist, but he totally doesn't want the humans to feel left out of the conversation!
R2D2, though, is like one of those really stand-offish people who deliberately talks to their friend in French or whatever whilst the rest of the group just stands around awkwardly.
Then C-3PO replies in human-language, to make a point. You're all about the social glue, C-3PO.

Best answer: Excellent point, sir! It was lazy, thoughtless anthropomorphising on my part, and I'm ashamed (but grateful) to be pulled-up on it.
Middling answer: Both George Lucas and Anthony Daniels have said that C-3PO was a dude, and in the Phantom Menace, Anakin says "He's a protocol droid," and Padme replies "He's perfect".
