Quote 1, from the series The Unwanteds:

Lani frowned. "Why would I want a third arm?"

"That's not the point," said Alex.

"Why would anyone want a third arm?" Lani went on. "Where would you put it? On your back? You'd always be uncomfortable sleeping, and I doubt it would be all that useful."

"Ms. Octavia makes it work with eight," Kaylee said. "She's very efficient."

"But she's not human shaped," Lani said. She thought for a moment. "I wonder how she sleeps? With all the arms splayed out, do you think?"
