Even though the son in "My Papa's Waltz" is dizzy, and keeps getting his ear scraped by his dad's belt, he clings to his father. This shows that he really looks up to and loves his father. We bet even mom gets some respect – her son is worried about that persistent frown on her face as the father-son romp makes pans go flying off the kitchen shelves.
Even though this dance is a little wild and scary for the boy, he holds on because he's having fun and really loves his father.
The boy's complete adoration of his father is unhealthy because his father is abusive, or at least careless with his son.
