This reasoning was actually very sensible, even carrying the particularly fitting old-age belief of "sacrificing two years for one's younger brother"...
Song Tan even gave herself a thumbs up.
But who knew, Grandma would take the road less traveled!
"You child! What are you saying? Is this how your parents taught you? Did I teach Wu Lan to think this way?"
Grandma looked solemn, with heartfelt earnestness:
"Tantan, you mustn't think like this. Qiaoqiao is Qiaoqiao, and you are you. If Qiaoqiao has difficulties, you give him a hand; if no one is there to take care of him, you help out so he doesn't go hungry... This is the affection between you siblings, it's your responsibility as a sister."
"But you can't just neglect yourself for Qiaoqiao! You've got to put yourself first to live a good life!"
A girl's youth is so precious!
