The commercial is about adoption, and becoming a parent to a child who's already a person. This is good, I support the message, and it's very positive. Then at the end they say "In Pennsylvania, thousands of children and their siblings need their love."
I KNOW what they mean. They're classifying teenagers as not children because what they need from the process is different, and because it is much more emotionally difficult to parent and bond with teenagers than the little ones. They're much less likely to find a home. And people considering adoption SHOULD think about taking siblings if they have the resources, because breaking up family units is bad.
What I hear is different. What I hear is "Thousands of orphaned children in Pennsylvania have adult siblings who aren't able to take care of them." While this may be true, I don't think it's the message they mean. Of course, when it is true, those are generally the ones who need it most. My aunt and uncle fostered teenage boys for about twenty years. They adopted 8 or 9 of them, including a set of three brothers. At least two of them weren't adopted until they were over 18, because their mother was alive and would not sign over parental rights. It's valid. Just... not quite what goes with the video of the five-year-old.
