Another random question from a four year old…

Kira: Daddy, did we adopt Scotch?
Daddy: What does adopt mean?
Kira: You know… When you save a pet?
Daddy: Oooh ok. Yeah we adopted Scotch.
Kira: That’s good, that means you saved him. Did you adopt him before I was here?
Daddy: Yeah Mommy adopted him before you were here.
