On Women’s Day, my father and I planned to give my mother surprise. We did something specially for her. Know that she was always unwilling to buy herself anything, we decided to buy him a perfect gift. In the shop, the shop assistant introduced a beautiful necklace, what I thought was the very thing for my mother. However, we bought it without hesitations. The moment we take out the necklace, my mother was very surprised that she could not say a word. This is my great pleasure that my mother likes the gift. I hope my mother will be happy and healthy forever.
