The students’ union will organize an activity when we can exchange items we don’t need with others. If you are interested it, you can join in between three and six on Saturday afternoon on the Central Road in our school. As a matter of the fact, many of us have difficulty deal with used things that mean little to us. If you take it there, not only can you get anything you want, but you can also help others. Beside, it will be a good chance to communicate and make new friend. Any used items is welcome, such as used books, shoes, watches. The more, the good.
