"He's already very ugly as it is..."
Niuniu kept muttering to herself.
Bending down, Liu Sisi spoke to Niuniu with earnest gravity, "What do you mean by 'very ugly'? He is your Third Brother, and as his Second Sister, what you should be doing is comforting him, not kicking him while he's down. If you were hurt, how would you feel if your Eldest Sister said this about you?" Of course, by Eldest Sister, Liu Sisi was referring to YingEr.
"Eldest Sister would never say that about me!"
Niuniu pouted as she spoke.
"If you know that Eldest Sister would never say such things about you, then why would you say them about Chou Chou? Think about it, did you do something wrong?" Liu Sisi imparted her lesson with serious import.
Niuniu slowly lowered her head and fiddled with her fingers in silence.
"Niuniu, it's okay to make mistakes. As long as you sincerely recognize your fault and strive to correct it, you're mom's good girl. Right?" Liu Sisi gently touched Niuniu's head.
