這是我高中時候的書包, 最近拿來當公事包. 當時是開學前, 跟外婆去買的, 那時店家的兒子有一題數學不會, 我順便幫他講解, 老闆娘就算我便宜一點.
This aged bag is working as my briefcase now. In fact, it is the bag I used during high school. I remember that grandma and I went for shopping a new bag several days before the term began. Finally, we bought this one at discount price as I helped the son of the shopkeeper to solve a math problem.
