[It's a little offensive, but Peridot lets her flat look speak for itself. She's on a roll here. No time to correct ignorance.]

Well, as a technician, my role used to be maintaining the Kindergartens that created new gems, but... Heh. Like I said, they drain planets of their actual resources. Other planets mostly have organic life, and Earth is full of it. There's so many things on it and they all live.

[Her voice rises an octave, excitement building again.] They just... thrive and they're not bound by a rigid caste system. They aren't born knowing what they're going to be from the day they emerge from the ground or-or whatever organic beings emerge from! Homeworld is... It's cold and harsh and everything is so structured... Which, admittedly, is nice. The chaos of Earth can be a little intense, but... but... I can be and do whatever I want. I would've never known I had metal powers if I hadn't decided to stay on Earth.
