I am So MAD!!!

I am so angry, I am so angry.........>>>>>> Today is my two assignments due date and both also are group assignments. One of the assignment, we have finished it before the exam; and another one is marketing assignment which I do not have enough time to do it. So I just start working on it on Wednesday night (after my 2nd exam). That night, I have already done my second part, which is the longest and toughest part. Then the next day afternoon, I already wanted to start doing my 1st part--summary, but the problem was I have to compile with my friend work first, then I still can do the whole summary. But my friend told me that she has not done yet, so I have to wait for her work then still can work on it again.
After reading and editing, I have finished it at 12 midnight. Therefore I think everything will be fine and I already plan Friday is my study and review day. Unluckily, I have gotten her call from this early morning and she told me I have done wrong and I have to redo again. Oh my god! this is the immediately thought that I have and why is me? So I really have to sacrifice my whole afternoon to redo again and it really make me so angry. I am very angry because she knows I have done wrong and why she doesn't want to tell me early or even yesterday night. I really can redo again whole night, but not whole afternoon. I really disappointing to her, I already give her many chance to persuade me to accept her. But why she still can be so selfish. Haiz...dont know need how many ice-cream or chocolate still can split out my anger.hehe...
