That's just immature, you don't know anything about me. Let's not fight about who speaks Japanese better than the other.
Furthermore, I've never said it's not ん, another funny conclusion you've come to. In パン, じゃん, like I said, any sentence that ends with ん, the ん isn't pronounced the same way as an English n. However, if you were to say パンです, the ん(ン) would have been pronounced the way an English n is.
