It was with Xiao AI.
"Big sister you own four cards and they are all complete, why did you think I took your card?"
1st elder didn't understand the situation so he asked. "Did you loose your card earlier today?"
Hannah nodded.
"Perhaps you didn't find it well." 5th Madam interfered. "But why would you think your sister tool it. You looked quite angry."
Hannah forced a smile. "Xiao AI and I play pranks like that on each other. So when I didn't find it I thought she must be pulling a prank on me. I should have searched well for it." She threw a stiff smile at Xiao AI who just shrugged her shoulders.
"So big sister, shopping next Saturday?"
"Of course little sis...of course." Although she wasn't quite satisfied she has no other choice. There were so many people and she couldn't ruin her perfect image herself.
"I will be awarding Group Z with 5 marks and group Y with 7 marks."
"Why do we get 5 marks."
