"Why can't I call you Lil Sun? Your name is Xu. Mommy said that Xu is a newborn sun. What else if it's not Lil Sun?"
Lil Ling'er was a little chubby since she had yet to escape from her baby fat. She looked much shorter than Lil Sun, but when she lectured Lil Sun, it was obvious that she was a veteran. It seemed like lecturing Lil Sun was something that she did a lot.
Lil Sun was hopping mad. "I told you it's not a newborn sun! The Sun exists in itself, and the Sun is a star. It's countless times bigger than Earth. How could it be a newborn sun?"
"That's what Mommy said!"
"Mommy said that 'Xu' is the rising sun, and the rising sun is the morning sun. How is it a little sun?"
