“I have an ipod” refers to a thing you own.
“I have a child,” or a spouse, or a dog, implies a relationship, a mutuality between sovereigns.
Ownership requires an object, an “it.” Relationship requires reciprocity. Always.
Ownership is unilateral. It’s mine. In relationship, something is always owed to the other. Always.
As a general rule, if a thing is alive, what you have is a relationship. Even if the law says otherwise.
