Reminds me of that scene from Super Mario RPG with Mallow who was adopted by frogmen.
“I’m a frog, but can you believe it? I can’t jump. Embarrassing huh?”
I was somewhere in between. I had been born for a while but still baby-ish, it wasn’t like Narnia where I was old enough to absorb it. My adoptive parents were a different ethnicity but looked enough like me to pass. Legend goes they told me about being second-hand parents early on and I was oddly skeptical enough that little me laughed in their face.
