Today PE lesson did a lot of excrise,very tired! But Siu didn't ,because she didn't bring her PE uniform. If I know this PE lesson is did excrise, I wouldn't change my uniform .After had PE lesson, I went to the changing room to change my uniform. I saw some form one student changed their uniform outside the changing room. Are they crazy? And I didn't want to see them anymore, I leaf quickly. I told Siu what I saw at the changing room. Siu said she saw the people was also doing something like that when she is in Japan...
