TOEIC ETS

29 July Shari MacCauley 103 Easton Lane Tomintoul, Ballindalloch AB37 9EX Dear Ms. MacCauley, It was a privilege to stay in your home during the week of 22 July as part of the Scottish Connections home exchange program. The location was the perfect setting for our family gathering. My daughter and son-in-law relished the peace and quiet of the village, while their children enjoyed playing in the wide-open space behind your home. And my husband was quite pleased with the large-sereen television set in the living room. It was very thoughtful of you to provide so many extra blankets. We did not expect it to be so cold at night in July. As I said in the note I left on your dining room table on 25 July, the day of my wedding anniversary party, the lid of your food processor cracked as we were preparing our meal. We ordered a replacement lid that same day, which should be delivered to your home soon, assuming it hasn't been already. I sincerely apologize for the mishap. I hope that you and your friends enjoyed our apartment here in Aberdeen just as much as we enjoyed your mountain home. If so, we hope you will be willing to exchange homes with us again in the future. Sincerely, Clara Brinwall Clara Brinwall
