Shallow for a kind

I guess no one will ever appreciate it… It all started with my sister grappling with her studies and her CCA. She’s always spending the day before her CCA making phone calls to her squad mates, polishing her boots, bothering about people’s hairnets etc. And my parents are not very pleased with the occurrence of her inability to cope with both, especially when she’s already busy with the immense workload from school. And from that, my mum diverted to me. And she starts going on and on about what the heck am I doing in JJC with my O Level score when I can easily get into ACJC or AJC. Then she starts criticizing my over-involvement in my secondary school CCA just to get 2 bonus points for it, when I have no use for it to enter JC. If that’s all she thinks of a CCA, she’s shallow.
