"Why Did I Do It?"

I regretted disobeying Ms Narwin, and now, where am I? Washington Academy. Actually I do not know how to sing the national anthem, but i did it deliberately. I refused to admit the truth as Ms Narwin is really treating me unfairly which cause me to have a grudge of her. I was thinking of a way to "punish" her. When she tried stop me from causing a disturbance, I thought that she had no right to do that, so I defied and even wrongly accuse her. Now, I am "forced" to sing the national anthem while my previous school, Harrison High, forbids it! At this moment, I finally appreciate the things Ms Narwin and other staff had done for me. If I had the chace to go back to Harrison High, I would surely apologise to Ms Narwin and all the other staff for giving a bad name to the school and causing them so much trouble.
