A
As a teenager, I felt I always let people down.
Once I left home for California with my' friend Penelope. The trip wasn't easy, and there were many times I didn't feel safe. When I returned home, I was different, not so sure of myself.
I was happy to be home. But then I notice that Penelope, who was staying with us, was wearing my clothes. And my family seemed to like her better than me. I told my mom, and she replied that Penelope was a lovely girl, but no one could replace (替代) me. I pointed out, "She is more patient and is neater than I have ever been." But my mother made me realize (意识到) that even with my mistakes, I was a loved member of the family who couldn't be replaced. When I became older day by day, I came to feel much more sure that no one can ever take my place.
Each of us holds a unique(独一无二的 ) place in the world. You are special, no matter what others say or what you may think. So forget about being replaced. You can't be.
