2. You Hurt Its Feelings
I’ll be honest here. This is really darn weird. Of course, parents would want to make life more fun for their kids, but anthropomorphizing a door like that to the point of making your child kiss it every time they slam it is a bit much. Some might think it’s kind of cute though, which is a fair perspective.
Is it supposed to be intended to teach them manners? Consideration? Empathy? It is better to learn it through dealing with actual people. I could be reading into it too much, though; it might have just been entertaining for the dad.
