As a teenager, I felt I was always letting people down. I was rebellious(叛逆)on the outside,      on the inside I wanted people to     .

I was happy to be home. But then I noticed that Penelope, who was       with us, was wearing my clothes. And my       seemed to like her better than me. I wondered if I would be       if I weren’t there. I told my mom, and she explained that       Penelope was a lovely girl, no one could       me.

She made me realize that even with my      , —and they were many—I was a loved member of the family who couldn’t be replaced.
