"Who said I didn't bring a letter back?" Yang Xiayun pouted.
"Heh, you call that a letter?" Yang Qingtong said while patting his sister's little head, "It's only a few words on a piece of paper, I can count them all. Big brother said that your 'family letters' never exceed fifty words. Are you even embarrassed to call that a letter? Have you seen the letters sister writes? She uses so many sheets of paper each time."
Upon hearing this, Yang Xiayun stuck out her tongue, "Hehe, Brother, you shouldn't nitpick so much. No matter how many or few words, you can't change the fact that it is a letter."
"You always have an excuse."
"Brother Qingtong!" Luo Linyu, who had come over with Yang Xiayun, saw the siblings hugging and didn't want to interrupt.
She waited until the two had finished speaking before saying anything.
