When I answered the telephone this morning, I (know) that the woman (dial) the wrong number. But it (take) her a long time to find out. She (say) her name (be) Mrs. Mills and (ask) if I I (be) Dr. Cooper's secretary. I (tell) her that she (not to get) the right number, but I (not to think) she (listen) to me. She (tell) me she (want) to cancelled her two o'clock appointment because her husband (be) ill and she (have) to car of him. I (tell) her I (be) very sorry to hear that, but she still (have) the wrong number. Then she (want) to know if the appointment (can make) for next week. I (tell) her it (cannot arrange) as I (be) not Dr. Cooper's secretary. Finally, she (hear) what I (say). She (want) to know why she (not to tell) right away that she (have) the wrong number. Before I (can answer) her, she (ring) off.
At first I (be) a little upset about it, but later on, in the evening I (decide) it (be) really quite funny. I (want) to trying my sister and (tell) her about it. It so (happen) that I (dial) the wrong number. And by a fantastic it (happen) to be Mrs. Mills. You can imagine how much I (astonish). I (try) to explain that I (make) a mistake, but she (not to listen). She just (want) to know how I (get) her telephone number. She (say) she (cannot understand) why I (bother) her. I (try) to explain again, but she (talk) so much and so fast that I (cannot interrupt) her even to say that I (be) sorry. Finally, I (hang up). I still (want) to speak to my sister, but I (be) afraid I (may) get that woman's number again. As a result, I (not to use) the telephone for the rest of the day.
