     Norah had a cottage on a cliff (悬崖) above a big bay. In winter it could be very unpleasant because

of strong winds and sea waves. In fact, when a gale was blowing, Norah and her husband got used to

sleeping in a small room downstairs, because their bedroom upstairs, which faced the gales, had a very

big window, and they were afraid that an extra violent wind might break it and blow pieces of broken

glass over them.

     Also, the salt wave from the sea put an end to many of the colorful plants Norah planted in her garden. She tried putting up a fence to protect them, but the wind just hit it, went up over the top and then down

come to enjoy the beautiful place, and in the end it really became quite annoying for the couple. When

they were at home, they found friends and relations arriving, expecting to be given unlimited drinks and

meals, and to sit in the sun for hours, talking as if Norah and her husband had nothing else to do but

entertain and listen to them.

     This went on for several years. Norah didn't wish to appear rude by refusing to let her friends and

relations in, but on the other hand, she was getting tired every summer.

Then one day Norah was complaining about this to her hairdresser while she was doing her hair. "You're

disturbed by too many uninvited guests, are you?" said the hairdresser. "Why don't you try my way of

escaping?"

     "What's that?" asked Norah.

     "Well," the hairdresser answered, "when the bell rings, I put on my coat and take my shopping bag. If

it's someone I don't want to see, I say innocently, 'I'm sorry, but I've got to go out.' But…
