Dear Mike,
We got your letter yesterday. Yes, we can visit you at Christmas. We thought to spend Christmas at
home, but now we are going to be with you. Jack will not be in school then. The weather in Chicago is
cold, but it doesn't matter. Sometimes we like the snow. We got our plane tickets. We will get to your city
on the 18th. We will stay with you for two weeks. Is that all right with you? We'll take our favourite
recipes (食谱), so we can have a nice Christmas dinner.
See you soon .
Love
Mom and Dad
