I used to go to supermarket with Mother in my youth.I always tried to buy some snacks.It cost about 10cent，but she didn’t buy them.Sometimes，only on my birthday，she said to me’Go and buy anything you like!!!”whenI heard such words，I always run to the snack corner and buy them as mane as possible.now I am an adult，and I can earn so I can buy anything.But when I see cheap snacks，I can’t help remembering those days.I was happy and now I am more happy with snacks.
