She want to raise the fight - How can she be so dumb

Few days back, my parents came home. Our fight was ongoing. So, we were in bad mood.

I wanted to buy my mom a new phone. Even in fight, I told her that I want to buy her a mobile.

And, I ordered one. After few days, I was sitting with my parents, kanika was also there.

I dont know on which thing, she bluntly told in front of my father that she is not aware that you are buying this phone, and her tone was so rude. She said this to make sure my parents listened to this.

I was furious to this. Lets say, she felt bad that I didn;t tell her that I've ordered it. She should have shared this with me alone. But no!
