Annoyed Day

On Saturday, when I went to school, I felt very sulky, because at that morning, I remembered that on that day was the time of picket. I direct cleaned the whiteboard after put down bag. Because when the time of picket, I always sweep alone. At that time I ask to clean just blackboard.
When I cleaned the whiteboard calmly, sudden, " Hanum, it’s the time for me to picket, too. Right?". I was very surprised. In the reality there was one of the my friend call. She is its time of clean class also. She was a lazy girl. She was very rare to sweep. Then she joint to clean board. When engrossing to clean, sudden she defile my clothes with the eraser of whiteboard. She did that purpose.
That time, I was very sulky. I felt want to be angry, because I do not like if my clothes is defiled. Saw my dirty clothes, she did not feel guilty, but smiled. Since that affair, I was getting far of her. I do not mean so, but I avoid her, because she’s too much to joke.
When going home school, my mother was angry to me. I couldn’t answer and just listened it. I feel so annoyed with her . Because she’s annoying. ‘Til this time, the ink which in the whiteboard eraser can’t be lose.
