Grounded

It is my first time I have been grounded so badly, and why? because of my bad grades. The first quarter of the year I have taken it with a lot of laziness and I have not been doing my home work. So now every after noon I have to stay for an extra hour at school and instead of arriving at 8:15am I have to arrive at 7:35am, I can not play xbox and my dad is about to take away my Mac which makes no sense since I still have my school computer, and I also have to catch up with all of the home works i did not do plus the ones I have to do without falling back in the other works. Oh and I also have to go to swimming twice a week.
