Dear Mary,
Thank you for your last letter.Here are photos of me and my sister Amy.As you can see,in some ways we look the same ,and in some ways we look different .W e both have black hair.But her hair is longerthan mine. We both have many friends.She is funnier than me.She's more outgoing.And I'm quieter.I am good at math and Chemistry.So I think I'm smarter than her.And her favorite subjectis Chinese.We both like reading books.However ,we both enjoy going tothe movies.Please write us soon!
Love,
Sarah
