Dear Linda,

     Thanks for your letter. I'm glad to hear you can come on Sunday. When you drive over to my house,

it's easy to find the station. It's a little difficult after that. So here are some instructions(说明): Drive past the station. Don't turn left into Garden Road. Just go along New Street. There's a football ground on your left. Go straight ahead, past the bank, and turn left into Green Road. Turn left again into High Street. River

Street is the first on the right. My house is on the right, across from a school.

     See you on Sunday!

                                                                                                                                                       Love,
