My own computer?

“What do you want as your 19th birthday present?” my mother asked me last May. Ｉ answered as a jest, “A computer!”. Now, I have my own computer! My parents really bought it as a 19th birthday present for me. When I opened the present, I was surprised very much. Although I couldn’t understand why they gave me such a big and expensive present, I was very happy to have my own computer. I thanked my parents so much. However, come to think of it, the computer isn’t mine at all. It is in the living room, and my family can use it whenever they want. Recently I noticed that my computer is not mine but my family’s in fact.
