Chi Enen understood what he meant and immediately followed, "I know, I know, my Baby Chi is the best."
"Hmph." Baby Chi snorted and mumbled in a voice that only he could hear, "You say I'm the best, but you still like The Neighbor Old Wang the most!"
He spoke so softly that Chi Enen couldn't clearly hear what he said.
But she did catch those last four words.
The Neighbor Old Wang.
Even with her toes, she could guess what Baby Chi meant.
She was amused and exasperated.
Really couldn't figure out what her Baby Chi was thinking all day long.
