Esperanto, the secret language
I feel compelled to point out that the only substantive objection I have to teaching Esperanto in public schools is that it will no longer be our secret language.
My beloved and I live in a part of the world where there are more spoken languages than there are craters on the moon. (This is only a slight exaggeration.) We are also inundated with tourists all year round. When we go out, we speak Esperanto as our “secret language.” Why? Well, of course, so that we can talk about other people without them knowing about it.
So if you see my beloved and me sitting on a park bench, speaking a language you don’t understand while furtively pointing at people and giggling, you can rest assured that we really are talking about you.
However, if Esperanto is taught in public schools, we’ll have to find some other amusement.

I would have thought the pointing and giggling would give you away whatever language you use
“Well, of course, so that we can talk about other people without them knowing about it. ”
Eble, sed mi nun povi komprenas vin!
