Nancy Bright and her husband John had been working overtime and saving for a long time so

that they could pay the advance for Nancy s dream house. Today was the day that they had enough money in hand to make a down payment on the house. But the real estate(房地产)agent informed them that she had received another offer for the house. Although the other offer was slightly less than that of Nancy and John s, that person with the new offer was willing to pay the whole amount at once. The owner,in urgent need of money,wanted to accept the second offer. Nancy and John looked at each other with disappointed looks. They walked back home feeling very low about having lost the house. Soon they recovered and involved themselves into their daily lives,though once in a while Nancy would sink into a mild depression over losing the house. One day Nancy woke up in the morning feeling even lower than usual. She kept feeling sick, even lost interest in her routine coffee. She put all these symptoms down to the stress of working hard and losing her dream house. A week passed and she seemed to get worse. John was worried and insisted on taking her to the doctor. The doctor, after taking a few tests, informed them with a huge smile that Nancy was two months pregnant! John and Nancy were overjoyed but also worried about not having their own house before the baby was born. One evening Nancy wandered into the street where her dream house was,and as she passed by it,she was surprised to see that there were notices stuck on all the houses. On closer examination she found that the notices were for all the residents to move out of the houses as they were building a highway and the whole row of houses needed to be pulled down. Nancy suddenly realized that not getting her dream house had been a blessing in disguise. She thanked God and decided to be happy with the blessings she had and started looking forward to the birth of her child.
