Demonstrates how little we know! Our inability to understand the relatively-simpler communication of other life on earth generally makes me think we would fail spectacularly if we ever meet aliens...
There was a movie where the aliens patiently let humans try to devise a way to teach a way to communicate, but they were teaching the humans a superior way of communicating the whole time. Would be a spoiler if I said the movie name and you hadn't seen it.
I wouldn't be surprised if various domestic and cohabiting animals feel that way about us. A lot of what we do is built around verbal nuance but isn't really necessary to get the same results in our daily routine, acquiring goods or hunting, or sex. Analogous to how adult cats do not vocalize to each other (at least in a frequency we can hear), or a person that is into you doesn't really care what you say only the tone. Our hierarchy of needs and wants are a shared protocol already, and it is communicable to other people that don't speak the same language, other mammals, birds, and cephalopods without speaking.
If you are talking about the movie that I think you are talking about, I don't think it is really so much about a superior way of communicating, just a different one.
As somebody who loves both, I recommend watching the movie before reading the short story; IMO there's something the viewer only gradually understands in the movie that's explicit up front in the story.
