You don't really understand human nature unless you know why a child on a merry-go-round will wave at his parents every time around–and why his parents will always wave back.

Tammeus uses a small, familiar scene to point to a larger truth about social life: people seek reassurance that they are seen, safe, and still connected. The child’s repeated wave is less about novelty than about checking the bond—“Are you still there for me?” The parents’ automatic wave back expresses reciprocal attachment and the pleasure of being needed. The merry-go-round’s circular motion becomes a metaphor for recurring human rituals—greetings, check-ins, and small courtesies—that continually renew relationships. The quote suggests that “human nature” is revealed not in grand declarations but in these repeated, almost instinctive exchanges of recognition and belonging.
