well, after two days study, we have the first weekend. we have a new classmate. when i first saw her she was downstairs.when the second time i saw her she was doing exercises in the corner of the classroom and when the last time i saw her she was still doing some exercises. and i don't know why she didn't talk to us. today is our maths teacher's birthday.we bought him a pen yesterday and put it in a gift box.then we put the box in a big box with bottles of water to increase the weight. and the teachers' day is coming, too. the surprise is beginning!
