单项选择题Bill and his family have been living in the same old building for eight years．The landlord (房东)also lives there,and usually all the tenants(房客) get along fairly well with one another．Recently, however,there has been a change in their relations．
A nice, quiet old couple used to live there, too．The old lady would sometimes bring some small cakes she made to Bill' s mother, who in return would give her some meat or help her with shopping．Unfortunately, the old lady died last month．As her husband couldn' t live alone, his grandson moved in．
The grandson,a youth of about twenty, has become a problem to Bill' s family because he is so noisy．Bill' s family members were used to peace and quiet, but the youth likes to listen to his radio late at night．Sometimes his friends came for a visit, and they also made a lot of noise．Everyone in Bill' s family has been bothered by the new comer and getting angry．
Bill' s mother once politely asked the old man if he was able to sleep well at night, but it seemed that he didn' t understand what she meant and so never spoke to his grandson about it．If he did, the grandson apparently didn' t listen, since things have not changed any．Everyone in Bill' s family agrees that something has to be done, but no one wants to hurt the old man' s feelings or cause him any
problems．
