your family member (...) not your kid

Aight, yeah, that's such a helpful and unambiguous distinction. For the last couple of years, I was confused whether my cat is my biological child and not just some creature I took into my home that's utterly dependent on me. I was wondering why he was doing so poorly in school and thought he had the ADHD, but that clarifies it. Thanks for this profound insight, I now only have to find out if the cat is maybe my brother or cousin, which I guess is still possible.
