How Do You Know the Ocean Is So Friendly?

So...the two of us are casually enjoying breakfast on the balcony of our room. She looks over and asks me this question. Of course, I go deep and start explaining that the ocean isn't always friendly - as there are sharks and other bigger fish (circle of life, yada, yada).

She gives me a few blinks and says.....

"Because it Waves!"

She cracks me up. It had to be several weeks ago that she and her daddy were reading a kid's joke/riddle book. She remembered and whipped it out in context. LOVE IT!
