"Look at you, so opportunistic. You pile praise on Qian'er when it benefits you, and then accuse her of being arrogant when it doesn't. You happily buy things for your sister, even asking for my help to choose..."
"Don't wrong me. I just grumbled a bit out of worry. I couldn't really do anything to her. Shouldn't I buy what needs to be bought? Even though I don't understand why women need so many bags..."
Eldest Sister-in-law glanced at him, "What do you know! It's an instinct for women to buy bags! In primitive times, women would carry baskets for gathering. So our love for bags is instinctive, and suppressing instincts is a source of family suffering!"
"...Why does this sound like something Younger Sibling would say?"
"Of course! Xiao Qian is so brilliant. After she came along, my mood has lightened up. Whenever I'm down, I look to her! Look at how natural I am now when I go bag shopping!" Eldest Sister-in-law likes Xiao Qian.
