If we could all communicate in sonar, and send out waves to find out where everyone else was, I think things would be better. No miscommunication, no misunderstandings. Just frequencies underwater bouncing off one another and coming back to tell you that you aren't alone. And what if we talked only in notes? Our highs and lows could mean all that we had to say. Or only in images, that you thought of and were conveyed instantly into the recipient's mind but they saw things slightly skewed, the way we understand others speaking now, only instead of words its pictures and there's no language barrier, no way to confuse entirely what's going on because even though its your interpretation of an image sent to you, there's still that basic idea of the image. Like if I was trying to say, "beautiful girl," and I sent you a picture of what I thought one was, and you got a different picture in your head but that's still what you thought a beautiful girl was, we'd be on the same page, right? Or we could talk through movements, like sign language with our whole bodies, moving together or separately and telling each other what we think and dream and want.
I still like the sonar idea best. I wanna speak like whales do.
