Wave Propagation

Here is what I will not say to you: let's go down to the sea. Here is something I will never ask you: do you remember? I might ask you if you can feel the contours, but don't worry if you can't; they are wobbly, like radio waves plucked by unseen hands. You were the one who threw the rock in the sawmill pond to teach me about wave propagation. It was not the first time I didn't understand what you were explaining, nor would it be the last. But I understand now.

Here is what I will not say to you: let's go down to the sea, where darker mysteries await me. Throwing a rock in the sea does not create a wave. The wave is already there and it will eat the rock, along with anything else stupid enough to penetrate its surface. Here is something I will never ask you: what did it feel like? You can tell me if you like, but I will not ask. I will offer you shelter with me in this dreary oceanside room but I don't expect you to join me.

Here is what I will say to you: hands can push with the force of rocks penetrating water. I don't need to say this to you, but I will.
