【C】 　　My mother gave me a pig pin as my birthday gift while I was eighteen. I’ve taken it with me for 20 years. When I’m in a bad mood, I’ll take a closer look at the cute pig. I know that beyond a shadow of a doubt I’ll have the courage to face the trouble and move on. 　　One time I rode a bicycle along the river bank, but I felt so tired that I didn’t notice the red light was on. Therefore, I ran through the red light, and was almost hit by a car. I was not sure whether the pig pin saved me. But the pig pin gave me a sense of safety. 　　Now my mother passed away, but I feel she is always with me because of the pig pin. Seeing it is like seeing my mother though she is not in the world anymore.
