One Saturday, I was doing my homework while it suddenly occurred to me that it was my mother birthday the next day. However, I forgot it complete. I was worried that I didn’t prepare any present to her. At that moment, the idea of online shopping came my mind. I clicked the mouse and search some famous shopping websites. Having compared the price of many dresses, I chose one with a reasonable price which I supposed Mum would appreciate it and bought it as soon as possible. The next morning I received the dress as expected without get out of my room. You see, online shopping has made our life much convenient and colorful.
