下面是某报刊登出的一封读者来信，请你以编者Cathy的身份给这位同学回信，并针对她的问题给出合理的建议。

Dear Cathy,

    Sherry and I are in the same class and she sits next to me. She is an excellent student and I can learn a lot from her. However, she talks so much that sometimes I can't pay attention to my studies. I want to change a seat with another girl, but I'm afraid it will hurt Sherry's feelings. What should I do?

Yours,

Winnie
