I'm sitting on a rooftop near the sea. A pair of waves comes and washes over the roop top, one right after the other, and nearly knocks me off. Before I have a chance to recover, the two waves come back from the other direction with the same force and almost knock me off again.

Nobody seems to be around to notice my heroism, but mom and dave (who is a small child of perhaps 6) are walking around the beach neighborhood.
