Woe unto those who care for children if they don't know the principle of "demand properties". Elevator buttons demand to be pushed. Light switches demand to be flipped. Large open spaces demand to be filled with activity and sound, and a paper clip sculpture demands to be climed.
Papa seems to be fine with this, but the old guy talking to Papa maybe not. Hard to tell whether his concern is the child or the sculpture or both. Anyway, all's well that ends well, and it did.
