Hey my friend, come up this bridge.
Look- how happy are the fish!
They swim about and freely they go.
But why you ask me how do I know?
Yes, you are right that I am not a fish
But you are not me, how do you know that I don’t know?
Yes, I’m not you and I cannot say that you don’t know.
But let’s go back to our original topic
That I’ve just told you that I’ve learned on this bridge:
Fish are happy in the pond.
