Note: You need to write a response to an e-mail that you will read. What your response needs to include is in the directions so make sure you also read the directions carefully. Dear Charlotte, I am writing to let you know that at last, we have moved to a bigger house! We just could not go on living in the two-bedroom bungalow now that the twins are growing up and the new baby has arrived. So we started looking - and one thing led to another and finally, here we are in our new home. I'm sure you'll like it. We have three bedrooms now and a very modern bathroom and kitchen. The kids are happy because there is more space with the big living room and the garden outside. But John is the happiest of all because he doesn't need to do much decorating. Why don't you come round this weekend and see what you think of our new place? We would all love to see you and if the weather is good we can have a barbecue in the garden. Our new address and phone number are below, so write to us and let us know when to expect you. Thank you for giving the matter your attention and I hope to hear your reply soon. Lots of love, Julia Direction: As if you are Charlotte, read the letter and give a suitable response.
