Language really isn't about information transmission. You speak a language in order to join the group that speaks that language.
With Esperanto conferences, it was the level of fluency. I sort of thought it would be like watching a video of "Chapter 1 Dialogue" in a language class, like "Where is the library?" But it was very fluid, like watching someone speak Spanish. So seeing that happen convinced me that it's a real language; it's not people playing dress-up with a different vocabulary.
When asked what impressed her the most in Esperanto congresses
If you decide to get into Esperanto, that means you're not listening to all the people who say, "Why not learn a real language?" or "Isn't that the crazy utopian cult thing?" So there's an element of eccentricity in that, but also an element of toughness. You can stand up to the judgment and negative reactions and do it anyway. There's something admirable in that.
