Mr and Mrs Bell are very forgetful (健忘的). For example, Mr Bell sometimes goes to his office
for work on Sunday morning, for he thinks it is Monday.  And Mrs Bell sometimes forget to cook supper
for the family.
       One summer they planned to fly to New York for their holidays. They got to the airport only ten
minutes before the plane took off. So time was short. But suddenly Mrs Bell said she must tell Alice, their daughter, not to forget to lock the front door when she went to school. As Alice was then at school, they
couldn't tell her about it by telephone. So they hurried to the post office. Mrs Bell wrote a short note to
Alice while Mr Bell bought a stamp and an envelope. Soon the note wa's ready. They put the stamp on
the envelope in a hurry and dropped it in the letter box, but suddenly Mrs Bell began to cry. The short
note was still in her hand. She had put the plane tickets in the envelope.
