As Christmas is coming, I plan to buy something for my parent. What I want to give back is a VIP card of a health club but neither of them is doing enough exercise. My father works very hardly as a teacher, spending most of his time at school. My mother loves reading and often bury herself in her books. Therefore, all of them should exercise more from now on.
I want to give them this card to express my love and thanks for them. I hope that they will be able to get relaxing in the health club and make more friends here. At the same time, I hope that they can take care their health.
