2 kids who look related are hanging out with 1 of them looking very emotional and hugging the other.
A couple of child relatives were hugging because they were happy to see each other.
Not all kids that look related are relatives. Just because kids are hugging does not mean it is because they were happy to see each other.
Just because 2 kids who look related are hanging out with 1 of them looking very emotional and hugging the other, doesn't mean they were hugging because they were happy to see each other.
Looking very emotional doesn't imply being happy to see each other. Kids who look related aren't always a couple of child relatives.
