What is this?

Woke up by the sound of thunder this morning. It was raining heavily and the thunder were so loud. So, as it was a Sunday, it's time to do my chores. Get up from bed, washed up, and get the broomstick. As I was doing the chores, I noticed that my sister was watching something on her phone secretly, using a pillow to cover the phone. As expected, it was some korean drama which her friends transfered into her 32 GB memory stick. *She spent $100+ on that* That wasn't the first time I saw her watching the shows in her phone. In fact, I saw this almost everyday. If she have good academic results, I won't mind letting her watch these shows. But it was a different case. She failed almost all her subjects for mid year exams, and still continue to spend the time watching these useless videos. I told her I would let my parents know about it, and guess what? She said that she have taken a video of me using computer late at night! I was seriously bewildered by this. She even go to the extend of getting 'prove' to catch me red handed? *For those of you who don't know, I have a curfew of 11 pm when it comes to using the computer*

Ah well. It's 10am now, and I completed my chores. Waiting my parents to be back and I shall see what will happen.

Hands up, pens down.
