Where did Lisa go for her vacation?

Lisa was an attractive young woman, and she always combed her hair neatly and wore pretty clothes. She worked in a small town and earned enough money to take a vacation in the mountains during the summer.
The first time that Lisa went there, she discovered that she hadn’t brought enough money. At first she was worried, but then she remembered that she had brought her checkbook with her and went to the bank to cash a check. The bank teller had never seen Lisa before, but he knew that a lot of people were stealing checkbooks and using them. So he said to her, "Can you identify yourself, please?"
Lisa had never been asked to do this in her home town, so she looked puzzled for a moment; but then she took her mirror out of her handbag, looked at it, and then said happily. "Yes, it is me. "
